**Pensamiento:**

Let me understand the board. There's a big black background (node 0) with dots (gray pixels). Sky blue regions (S) form rooms. Green (N) objects are 21-pixel blocks — these look like 2x2-ish blocks with dark dots? Actually N pixels 21 each. There are 7 green blocks: 3 at top-left (rows 1-4, cols 14-16, 20-22, 26-28), and 4 at rows 13-16, cols 32-34, 38-40, 44-46, 50-52.
There's a blue (b) 6-pixel object at rows 37-40 around cols 20-21, and yellow (Y) 2 pixels at rows 38-39 col 22. So the player avatar is the blue thing with yellow? Looking at the image, at around (380, 420) px there's a blue character with yellow. So the player is blue+yellow.
The goal is likely to move the player to something, or push blocks? Let's look at the layout: sky blue rooms:
- Node 1: S 276 pixels at rows 0-11, cols 31-53 (top-right room).
- Node 90: S 1529 pixels at rows 19-... big bottom room.
- Also there should be a middle room rows 19-29? Actually node 90 boundary shows [[19,13],[19,53],[29,53],[29,48]] — it's a big object with complex shape, includes the middle horizontal room (rows 19-29, cols 13-53) and the bottom room.
Wait, the image shows: top-right room rows ~0-11 cols 31-53; middle room rows ~19-29 cols 13-53; bottom big room rows 36-62 cols 13-54. And the player is at rows 37-40, col 20-22 in the bottom room near the top-left of it.
Green blocks: 3 in top-left area (rows 1-4, cols 14-28) which are on black background? Hmm, they're at rows 1-4 which is in the top region; the top-right r

**Pensamiento:**

So green blocks are 5x5 (rows 1-5, cols 14-18?) Let's see: row1: cols 13=G,14=N,15=N,16=N,17=G... Actually node 5 boundary [[1,14],[1,16],[2,17],[4,17]] with 21 pixels: it's a plus/cross shape? 21 pixels: 5x5 minus corners = 21? 25-4=21. Yes, a 5x5 with corners dark gray (the G corners are separate 1px nodes). So green blocks are 5x5 squares with dark corners — decorative "bricks".
Player: blue shape at rows 37-41, cols 19-22 roughly:
```
row37: .BBbBB  (cols 19-22: B B b B? let me index)
```
Row 37 cols 16..28 = "SSSBBbBBSSSSS" so col16=S,17=S,18=S,19=B,20=B,21=b,22=B,23=B,24=S...
Row 38: "SSSBbbYBSSSSS": col19=B,20=b,21=b,22=Y,23=B
Row 39: same
Row 40: col19=B,20=B,21=b,22=B
Row 41: cols 19-22 = B B B (all black)
So the blue shape is a plus: (37,21),(38,20),(38,21),(39,20),(39,21),(40,21) = 6 px. And yellow is 2 px at (38,22),(39,22) — a "flame"? Blue plus with yellow on right side. Hmm, it's surrounded by black (B) at cols 19-23 which is the black background... wait no, the player is inside the sky blue room, but surrounded by black pixels. That means the player has a black outline/halo? Odd. Actually maybe the black is a hole in the room (like the player is inside a dark pocket), and the yellow is an exit/flame.
Hmm. Maybe the player is a small character with black outline drawn on top of the sky. But the outline is black and the background dots pattern... Let's check the black region: node 0 is the black background with 1894 pixels and children include lots of nodes. The

**Pensamiento:**

Interesting. The player (blue plus + yellow) is at rows 37-41, cols 19-23 with a black halo. The black halo is a 5x5-ish black square around the player, disconnected from... hmm, is it connected to the outer black? Rows 37-41 at cols 19-23:
row37: 19=B,20=B,21=b,22=B,23=B
row38: 19=B,20=b,21=b,22=Y,23=B
row39: same
row40: 19=B,20=B,21=b,22=B,23=B
row41: 20=B,21=B,22=B
So the black halo is a 5x5 block (rows 37-41, cols 19-23) minus... row37 cols 19-23 = B B b B B; row 41 cols 19-23? From row 41 string: "BSSSSSSSBBBSSSS..." col12=B... let me recount. The printed string starts at col 12. Row 41: index 0 = col12 = 'B', then S x7 (cols 13-19), then 'BBB' cols 20,21,22, then S... So row 41: cols 20-22 black.
Row 37: 'B' col12, then SSSSSS cols13-18, then 'BB' cols 19,20, 'b' col21, 'BB' cols22,23, then S...
So the black halo is rows 37-41, cols 19-23 forming a plus-ish/diamond black region, with the blue inside. It's a self-contained black pocket (not connected to outer background) — but segmentation said node 0 has 1894 pixels and children many. Hmm, if the black halo were separate it would be its own node. It's not in the node list (only one B node: id 0). So the halo IS connected to the outer background somehow... Or maybe segmentation merged them because of 4-connectivity through some path. Let's check: row 37 col 19 = B; row 36 col 19 = B? Row 36 printed: "BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBSSSSSBBBBBBBB" starting col12 — all B from col12 to col40, then S cols 41-45, then B. So

**Pensamiento:**

LEFT moved the player 5 cells left (from col ~21 to col ~16) and flipped it (rotated_by 180 — the yellow flame now on the left side). So the player is a rocket/jet that moves 5 cells per action in the direction it faces? Interesting: the yellow is exhaust; when facing right, exhaust is on right? Actually before LEFT: blue plus at cols 20-21, yellow at col 22 (right side). After LEFT: yellow at col 14 (left side), blue at 15-16. So the exhaust is behind... wait if moving left, exhaust should be on the right side. Hmm, before LEFT the exhaust was at right (col 22) and it moved left. After LEFT, exhaust is at left (col 14) meaning now it faces left... hmm confusing.
Let me reconsider: maybe yellow is a "headlight"/direction indicator, and moving LEFT flipped it to point left. So it now faces left. Then pressing LEFT again would move further left by 5? Or maybe the movement is 5 cells because it moves until blocked? Actually 5 cells: from col 21 to col 16, exactly 5. The transient bbox [37,15,41,20] indicates the animation traversed those cells.
Hmm — maybe the player moves 5 cells per step. Also the top-left area: the player was at cols 19-23 originally, moved to cols 14-18. Now it's at the left edge of the bottom room (col 13 is the room's left boundary? bottom room spans cols 13-54). Actually the player is now at cols 14-18 approximately, near the left wall.
Wait, importantly: the player moved left and stopped at 5 cells, not at wall. Let me check the current position precisel

**Pensamiento:**

Player now at rows 37-41, cols 13-17: blue plus at cols 15-16, yellow at col 14 (left). So the player faces left now (yellow = flame at back? or nose?).
Hmm, actually yellow is likely the flame/exhaust. When facing right (before), flame was at right... that's weird. Unless yellow is the "nose/front" and the player moved left while facing right — meaning the direction key moves the player in the pressed direction regardless of facing, and facing follows the last movement direction (so now facing left, flame should be at right...). Hmm, before: blue at cols 20-21 rows 38-39, yellow at col 22. After: yellow at col 14, blue at 15-16. So the whole sprite flipped (mirror) and moved 5 left.
So the sprite: blue plus shape with yellow 2-cell block attached on one side. After LEFT, yellow is on the left = the direction of movement. So yellow is the front/nose pointing in the movement direction. Good: yellow indicates facing = last movement direction.
Now, the room: bottom room. The player is at rows 37-41 which is near the ceiling. The player can move LEFT/RIGHT (and maybe the world has gravity? no UP/DOWN).
Goal: probably to reach/collect the green blocks? Or the goal is to reach the top-right sky room?
There's a purple pixel at (63,0) — the step bar at bottom-left. Row 63: 'p' then W's. So the bar grows rightward? Or the white bar shrinks from the left. Let's monitor.
Now, how does the player get to the green blocks? The green blocks are at rows 1-5 cols 13-29 (top-left, on black) an

**Pensamiento:**

RIGHT moved the player back to cols 19-23 (the starting position), not to the right wall. So it's not slide-until-wall; it moves a fixed 5 cells per action. From col 14 → col 19 (+5). And LEFT moved from col 19 → 14 (-5). So fixed step of 5 cells. Interesting: 5-cell grid steps.
Hmm, so the player teleports/moves 5 cells per press. Wait, but that first LEFT moved exactly 5 too. OK so movement = 5 cells per press.
The step bar: 'p' grew from 1 to 2 pixels at bottom-left; W shrank. So a bar counting steps — probably the budget. Row 63: p at cols 0-1, W cols 2-63. So the bar fills rightward: each step adds one purple. 64 steps budget? Or it's counting up.
Now: the player moves in 5-cell increments horizontally. The sprite occupies rows 37-41. To reach other rooms it needs vertical movement. Maybe MOUSE does something like a jet/flap (flappy bird?). Or maybe the sprite is a "rocket" that goes up when you click?
Hmm wait. Maybe the sprite moves 5 cells because the grid cells of the "world" are 5x5? Like the world is a coarse grid where each tile is 5x5 pixels! The rooms are made of 5x5 tiles. Let's check: bottom room rows 37-62 (26 rows), cols 13-54. Hmm, 13 = 13, 54 = 13+41. Not a multiple of 5.
Actually the sprite moved 5 = its own width. Maybe it moves by its own size.
Let me test MOUSE. Where to click? Perhaps clicking a cell makes the sprite move there or shoot. Let me first test clicking on a distant cell, e.g., the shaft at (33,43), and see what happens. Risky but informati

**Pensamiento:**

MOUSE at (5,40) was a NO-OP (only the step bar changed). So clicking on empty sky does nothing. The step bar advances with every action regardless.
So the movement animation shows the sprite moving 1 cell per animation step, 4 steps for RIGHT? Hmm, the animation showed the sprite moving from col 14 to col 19 = 5 cells over 4-5 steps. So each press moves exactly 5 cells (or the sprite moves continuously with 1 cell per frame and the action covers 5 cells).
Hmm, wait. Maybe the sprite moves 1 cell per action but the animation... no, the final position was 5 cells right of the start.
Hmm, actually maybe each press moves 1 cell but the animation frames I saw were intermediate... no, the final position diff was 5.
OK so 5 cells per press. Weird but fine. Maybe the sprite is on a coarse 5-cell grid... but positions col 14→19 → 24... Let's verify: LEFT from 19 to 14, RIGHT from 14 to 19. Consistent with 5-cell steps.
Now, what about vertical movement? There's no UP/DOWN. Maybe the sprite falls due to gravity when it moves? Or maybe the sprite moves in the direction it faces and LEFT/RIGHT rotate it? Hmm: LEFT rotated 180 and moved left.
Maybe MOUSE on the sprite rotates/launches it? Let me try MOUSE on the sprite itself (row 39, col 21).
Alternatively, maybe the game is like "the sprite slides and the level goal is to reach the exit / collect all green". The green blocks are unreachable horizontally in the bottom room... unless the sprite can leave the room through the shaft (cols 4

**Pensamiento:**

MOUSE on sprite = no-op. So MOUSE seems to do nothing here (maybe it's for other levels). The step bar is filling: 4 purple pixels after 4 actions. So it's a step counter/budget.
Let me reconsider: maybe LEFT/RIGHT move the sprite 5 cells, and the sprite CAN move vertically via... hmm. What if the sprite moves horizontally until it hits a wall, and 5 was coincidental? From col 14 pressing RIGHT went to col 19, but the room extends to col 54. So it's not slide-to-wall. Unless... hmm! Wait. What if the sprite moves until it hits an obstacle OR a fixed max distance of 5? Like a "5-cell" move limit.
Hmm, another idea: this is a "snake"/"worm" game where the sprite moves continuously? Let's check: does the sprite move on its own over time (each action it advances)? Let me check whether the sprite moves without input. Actually the diff between step 3 and 4 (MOUSE no-op) showed no sprite change. So no autonomous movement.
Hmm, what if pressing LEFT/RIGHT repeatedly moves the sprite 5 cells each, and the sprite's row changes when it encounters a wall — like it "climbs"? Let's test: press RIGHT several times and see what happens near the right wall. Let me batch RIGHT x 8 and watch positions. The bottom room spans cols 13-54, so from col 19 (bbox 19-23): +5 each → 24,29,34,39,44,49,54? At col 49 the sprite would be at cols 49-53; the room's right edge is col 54 (col 55 = wall). Hmm, then maybe it stops or gets blocked.

Wait — the sprite was already at cols 13-17 (after the first LEFT), then RIGHT moved it to 19-23, and now LEFT moved it back to 13-17. So it's at cols 13-17 again. It is flush against the left wall (col 12 is wall). Now press LEFT again to test if it's blocked or drills through.
Note the step bar is now 5 purple pixels. Let me count how many total: row 63 W count = 59. If the budget is 64 steps, we have ~59 remaining. Each action consumes 1.
Let me test LEFT once more.

## Paso 7 · nivel 1 · acción 6

**Pensamiento:**

Confirmed: LEFT against the wall is blocked (bounce animation, no net move). So movement is 5 cells per press, blocked by walls.
Now the puzzle: the sprite is in the bottom room. Only horizontal movement. The goal? Maybe to reach the shaft at cols 41-45 to go up... but no vertical control. Unless the sprite automatically moves up when aligned with the shaft? Hmm.
Wait. Maybe the sprite moves in the direction it FACES, and LEFT/RIGHT rotate it 90°? No — LEFT moved it left while flipping.
Alternatively: maybe the sprite can only move 5 cells but the rooms are aligned to a 5-cell grid, so the sprite is essentially on a coarse grid. To move up, maybe there's an action... Only LEFT/RIGHT/MOUSE/UNDO.
Hmm, maybe the sprite is on a coarse grid where each cell is 5x5, and the maze is a coarse maze. Let's map the maze into 5x5 cells. The bottom room: rows 37-62 (26 rows) — not a multiple of 5. Hmm.
Let me look at the whole board again in coarse terms:
- Bottom room: rows 37-62, cols 13-54.
- Middle room: rows 19-29, cols 13-53.
- Top-right room: rows 0-11, cols 31-53.
- Shaft (cols 41-45, rows 30-36) connects bottom & middle rooms.
- Green bricks: rows 1-5, cols 13-29 (3 bricks) and rows 13-17, cols 31-53 (4 bricks).
Hmm, the middle room rows 19-29 is 11 rows tall. Green bricks at rows 13-17 are just above the middle room, and the top-right room is at rows 0-11 just above those bricks. So the bricks form a barrier between the top-right room and the middle room (at cols 31-53), and the

**Pensamiento:**

Now precise: sprite blue at (37,15),(38,15),(38,16),(39,15),(39,16),(40,15); yellow at (38,14),(39,14). Black border: row37 cols 13-17, row38 cols 13,17, row39 cols 13,17, row40 cols 13-17, row41 cols 14-16.
Wait, row 37: cols 9-14 = B (wall + border), col15=b, col16=B, col17=B, col18=S. So the border extends to col 17 on the right and to col 13 on the left. Row 38: col13=B? "BBBBBBYbbB" from col8: col8=B,9=B,10=B,11=B,12=B,13=B,14=Y,15=b,16=b,17=B. So col 13 = B (border) and col 12 = B (wall). Both black, indistinguishable. Row 41: col13=S, cols14-16=B, col17=S. So the sprite's bottom row is 14-16 and its bbox is cols 13-17.
So the sprite bbox = cols 13-17, rows 37-41. Initially bbox was cols 19-23 (row 41: cols 20-22, row 37: cols 19-23). So the move was 19→13 = 6 cells? Let me verify the initial row 37: "BSSSSSSBBbBBSSSS" from col 12: col12=B, 13=S,14=S,15=S,16=S,17=S,18=S,19=B,20=B,21=b,22=B,23=B,24=S. Yes bbox 19-23.
Hmm, so the sprite moved 6 cells left, from bbox 19-23 to 13-17. And the blue moved 5 (from bbox 20-21 to 15-16) because the blue shape mirrored within the bbox: initial blue bbox 20-21 (with the tail at 21), mirrored so that... hmm, mirroring a shape about a vertical axis maps bbox [a,b] to [W-1-b, W-1-a] within the sprite's 5-wide bbox. The blue shape spans columns {21, 20-21} in the initial (relative to bbox 19-23: cols 2,3). Mirrored: cols 1,2 → absolute 20,21 for the same bbox. So mirroring alone doesn't change the blue bbox. Since the blue bbox moved b

**Pensamiento:**

Excellent! MOUSE on the green brick at (15,33) DESTROYED it! The brick at rows 13-17, cols 31-35 disappeared (became black), and the top-right room (S at rows 0-11, cols 31-53) merged with... wait, "appeared B 668 at [0,36] bbox [0,36,62,63]" and "disappeared S 276 at [0,31]". Hmm, the top-right sky room disappeared and a big black region appeared at cols 36-63?! That's confusing — probably the segmentation re-merged things. Let me look at the image: the top-right room now extends further (rows 0-17?) and the brick row now has only 3 bricks (the leftmost one gone), and the room above merged with the middle room.
Looking at the new image: the top-right sky region now spans rows 0-~18 cols 31-54 (the first brick's cell became sky). Hmm, but the diff says the S 276 disappeared and B 668 appeared at cols 36-63. That's just segmentation re-matching artifacts.
Let me get a clean picture of the current board: crop rows 0-20, cols 28-56.
So the mechanic: MOUSE clicks a green brick to destroy it (or to open a path?). And the goal might be to make a path for the sprite? But the sprite can't move vertically...
Hmm wait. Maybe the goal is: the sprite needs to reach the top-right area, and the bricks are barriers. Clicking removes bricks. But the sprite still can't move up.
Hmm, maybe the sprite CAN move up/down: maybe the sprite moves in the direction of the last press by 6 cells... no, only LEFT/RIGHT exist.
Unless... the sprite moves horizontally, and when it hits the wall it stops; bu

**Pensamiento:**

Now clear: the destroyed brick cell (rows 13-17, cols 31-35) became SKY (S), connecting the top-right room (rows 0-11, cols 31-53) with the middle room (rows 19-29, cols 13-53) via the column range 31-35 at rows 12-18.
So the mechanic: clicking a green brick removes it and turns that cell into sky (S), i.e., it "opens" the maze.
Hmm, but why does the sprite exist? Maybe the sprite must reach the top-right room (the goal = exit). And the bricks are the only barriers. The sprite needs vertical movement... 
OH WAIT. Maybe the sprite DOES have gravity/floating and moves 6 cells in the pressed direction, but the sprite's vertical position is determined by... hmm.
Hmm, let me reconsider: maybe the sprite isn't in the bottom room at all. Maybe the sprite is at rows 37-41 because it's "stuck" in the black. Maybe the sprite is a "drill" that can move through the black region (walls) — no, LEFT was blocked by the wall.
Hmm, hold on. Let me reconsider whether the sprite is blocked by the wall or by something else. At the left wall (cols 13-17), pressing LEFT was blocked. The wall at col 12 is black dotted. But the sprite started inside a black pocket (rows 37-41 cols 19-23 surrounded by black). So the sprite can exist in black. Hmm, but the pocket moved with the sprite.
Actually, maybe the black pocket IS part of the sprite (its outline), as I thought.
Let me test vertical movement: is there any chance that pressing LEFT/RIGHT when at a wall makes the sprite move vertically? No, it was

Confirmed: pitch = 6. Sprite bboxes: 13-17 → 19-23 → 25-29. So positions L = 13 + 6k: 13,19,25,31,37,43,49. Max L such that L+4 ≤ 54 → L ≤ 50. So 49 is the max reachable (49-53), and 55 would be blocked. Hmm, the room's right edge is col 54? Let me check: row 19: "BBBSSSS...SSSBBGB" — from the crop at cols 10-57: row 19 has S from col 13 to col 53, then B at 54. Let me verify: row 19 string index: position 0=col10='B',1=col11='B',2=col12='B',3=col13='S' ... The S run: cols 13-53, then col 54='B'? The string row19 = "BBBSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSBBGB" length 48 → cols 10..57. B(10),B(11),B(12), then S x41 → cols 13-53, then B(54),B(55),G(56),B(57). Yes, room cols 13-53.
So max L = 49 (cols 49-53). Reachable L: 13,19,25,31,37,43,49. The shaft is at cols 41-45 → needs L=41. Not reachable. Hmm!!
So the sprite cannot enter the shaft at cols 41-45... unless the sprite is only 4 wide for collision? Its halo is 5 wide.
Hmm, wait. But maybe the sprite doesn't need to enter the shaft — maybe the goal is something else entirely.
Let me reconsider the whole game. Maybe the sprite is a "cannon" that fires in the direction it faces, and MOUSE... no, MOUSE destroyed a brick directly.
Alternatively, maybe the sprite is just an avatar and the actual goal is to destroy all green bricks. Let me test: click another brick and see if the level progresses. But maybe the goal is to have all sky regions connected — already done, no win.
Or maybe the goal is to make the sprite's sky reg

**Pensamiento:**

Clicking sky cells = no-op. So MOUSE only affects green bricks (destroys them → sky).
So the current model:
- LEFT/RIGHT: move sprite 6 cells horizontally, blocked by non-sky.
- MOUSE: destroy a green brick (turns it into sky).
- Step budget bar at the bottom (64 steps?).
Goal hypothesis: get the sprite to the top-right room (or to the top of the board). The sprite needs to move up, but there's no UP action. Hmm... unless the sprite rises automatically when the sky above is open? We haven't tested that: the freed passage is at cols 31-35 and the sprite is at 25-29. Let me move the sprite to L=31 (one RIGHT) and see if it rises. That's a cheap test (1 action).
Wait, but why would the sprite rise? Maybe it's a bubble/balloon with buoyancy. Or maybe the sprite is a rocket that rises when unobstructed? Hmm, but it didn't rise at the start (the ceiling above it at rows 30-36 cols 13-40 is solid black — so it was blocked; consistent with buoyancy!). Interesting: the sprite is at the top of the bottom room, right under the solid black ceiling. So buoyancy is consistent with all observations so far!
Test: move to L=31 (aligned with the freed passage) and see if it rises. If buoyancy, it should rise through the passage into the top room until it hits a ceiling.
Let me do RIGHT then observe.

```python
r = action(['RIGHT'])
print(r['gameplay_changed'], r.get('animation'))

**Pensamiento:**

The sprite is now at cols 31-35, rows 37-41 — aligned with the freed passage at cols 31-35 (rows 12-18). But it did NOT rise. So no buoyancy (at least not automatically after a horizontal move).
Hmm. So how does the sprite get up? The passage from the bottom room to the middle room is the shaft at cols 41-45 (rows 30-36). The sprite can't align with it (needs L=41, reachable L are 13,19,25,31,37,43,49).
Hmm, unless the sprite can move up via a mechanism I haven't discovered. What if the sprite moves up when the sky above it is created by clicking? E.g., the sprite rises when a brick directly above is destroyed?
Or maybe the goal isn't vertical navigation at all.
Let me reconsider the game completely. What if this is a "sink/flood" game where the goal is to make the sprite DROWN or to fill the room? Hmm.
What about the possibility that the goal is to remove ALL green bricks? Let me just do that and see if the level completes. 5 clicks remaining (3 top-left, 3 in the row = 6 total? Let me recount: bricks at rows 1-5 cols 13-17, 19-23, 25-29 (3), and rows 13-17 cols 37-41, 43-47, 49-53 (3). Total 6 remaining).
Before that, let me think about whether clicking is the intended mechanic or whether the sprite should do it.
Alternatively the goal might be: "connect the sky regions so that the sprite's region touches the top edge" or "the sky must reach the top-right room" — already done.
Hmm, what about the goal being to make the sky region contiguous with the top-left bricks area? Th

All 7 bricks destroyed (greens_left 0), no level completion. Interesting: the destroyed bricks became sky, and the sky regions merged. But the level isn't complete.
So the goal isn't "destroy all bricks". Hmm. And the sprite is still stuck.
Let me re-examine: after all bricks removed, the sky region is one big connected area covering the top-left (rows 0-5, cols 13-29), top-right, middle, and bottom rooms. The sprite is in the bottom room at cols 31-35, rows 37-41.
Now the only way up is the shaft at cols 41-45. Hmm.
Wait... maybe I should reconsider the sprite's movement: maybe the sprite's movement is not fixed at 6 but "6 or until blocked"? We saw it move exactly 6 in open space. At the left wall, it was blocked entirely (no clamping). Hmm.
But what about the shaft: the sprite needs to be at cols 41-45 to pass. Reachable L ∈ {13,19,25,31,37,43,49}. Hmm.
Unless the sprite can move diagonally/up as part of the horizontal move when there's a hole? No.
Hmm, what if the sprite can move up through a 1-cell-wide...
Let me reconsider the game objective. Maybe it's "flood fill": the goal is to make the sky cover the whole board? Not possible.
Maybe the goal is to make the sky region touch the top edge? Already true (top-right room touches row 0).
Maybe the goal is to make the sky touch ALL edges? Left edge? The sky spans cols 13-53, never touching col 0 or col 63. Bottom: row 62 is S (the bottom room extends to row 62; row 63 is the white HUD). Top: row 0 ✓.

Whoa! The board changed dramatically! Green bricks have APPEARED in new places, and the layout looks different! Let me look at the current image:
- Top: a big sky region rows 0-17ish cols 13-53, with 3 green bricks inside at rows ~8-12, cols 25-41.
- Middle-left: 6 green bricks in 2 rows at rows ~22-32, cols 13-29.
- The sprite is at the right side, around rows 37-41, cols 49-53.
- Bottom: sky region.
Wait, this looks like the whole board changed. Hmm! The diff image (step 19→22) shows changes in many places: a sky block at top-left, green bricks appearing in the middle-left (2 rows of 3), a brick row at top-middle, and the sprite moved.
Hmm, so the bricks MOVED? Or new bricks spawned? Let me look at the diff image more carefully: it shows changed cells in their new colors. At the top: a sky rectangle at rows ~5-12 cols 13-30 and green bricks at rows ~8-12 cols 25-41. In the middle: green bricks at rows 22-32 cols 13-29 (6 bricks), a sky 5x5 at rows ~27-32 cols 29-35, a black 5x5 with dots at rows 22-27 cols 43-47, the sprite at rows 27-33 cols 49-53. And a black region at rows 38-48 cols 13-29.
Hmm, that's confusing because the diff shows the union of 3 actions' changes.
It seems like the WORLD shifted! Maybe pressing RIGHT moves the world left (i.e., the sprite stays and the maze scrolls)? No wait, earlier the sprite moved and the maze stayed.
Hmm, but now the maze changed a lot. Maybe the maze is SCROLLING: when the sprite reaches the right edge, the world shifts? Or maybe

Now I see: there are new bricks at rows 13-17 cols 25-41 (3 bricks) and rows 31-35 cols 13-29 (3 bricks) and rows 37-41 cols 13-29 (3 bricks). And the S region at rows 1-29 cols 13-53 (1056 px) and rows 37-62 (701 px).
Wait, this is a completely different board! The bricks have moved/regrown, and the layout changed. Hmm! And the sprite is at cols 49-53 rows 37-41.
Hold on. Maybe I'm misreading: maybe the level RESTARTED (game over → reset)? No, game_over=False.
Hmm, what happened? The last 3 RIGHT moves: the sprite went 31→37→43→49. But the board changed massively between step 19 and 22. Wait, at step 19 I had removed all bricks (greens_left=0). Then 3 RIGHT moves, and now there are 9 bricks?! And the top-left area (rows 1-5 cols 13-29) is now sky (part of the S 1056 region at rows 1-29).
So bricks SPAWNED in the meantime. And the middle room changed: previously the middle room was rows 19-29; now the S region covers rows 1-29 (merged with the top area). And new bricks appeared at rows 13-17 cols 25-41 (inside the sky region!) and at rows 31-35 and 37-41 cols 13-29 (in the black wall area between the middle and bottom rooms).
So bricks grow/appear over time! Each action (step), new bricks may appear. Perhaps the sky is being consumed by growing plants (green bricks), and the goal is to keep the sky open / prevent the plants from taking over? Or the bricks spread from... hmm.
Alternatively, maybe the bricks are "spreading" like a virus: after I removed all bricks, they regrew

Hmm, so the frame at step 20 (after the first RIGHT) had green 0 but sky decreased by 233. Then step 21 had 9 bricks.
Wait, my history indices: history[-8] is step 15... and the last three entries are steps 20,21,22 = the three RIGHTs. So after RIGHT #1 (step 20): green 0, sky 1823. After RIGHT #2 (step 21): green 189, sky 1757. After RIGHT #3 (step 22): same as step 21 (no change except sprite? but the sprite moved in the third RIGHT...).
Hmm, confusing. Let me check the sprite position at each of those steps. Actually the sprite is at cols 49-53 now, and the third RIGHT moved it 43→49. But green/sky counts identical at 21 and 22 → the world didn't change in step 22, only the sprite moved. And in step 21 the world changed (bricks appeared). And in step 20 the sky dropped by 233 without bricks appearing — 233 = ? Hmm, 233 cells of sky became black? That's about one brick area (25) plus... Hmm.
Let me look at the transitions in detail: for each of the last 3 transitions, get the diff summary (appeared/disappeared components).

```python
for t in transitions[-3:]:
    d = frame_diff(t.before_frame, t.after_frame)
    print('---', t.action, 'step', t.after_frame.step, 'changed', d['changed_cell_count'])
    for k in ('moved','appeared','disappeared','resized','changed_color'):
        for e in d.get(k, [])[:6]:
            print('   ', k, {kk: e[kk] for kk in e if kk in ('color','pixels','at','bbox','from','to','before_pixels','after_pixels')})

Wait, huge revelation: at step 20, `p` resized from 19 to 213 pixels! And W from 45 to 44. And at step 21, p went back from 213 to 21. Hmm, that's the purple bar. 213 pixels of purple?! That's not a bar on row 63 (only 64 cells). So the purple appeared elsewhere — maybe a purple overlay/flash animation (transient). Hmm, `p` at 213 pixels in the frame at step 20... but the current frame's p is 22.
Hmm, wait. Actually maybe the purple flash is a "level complete" flash! Let me check: at step 20, p=213 pixels. Hmm, but level_completed was False.
Hold on. Let me re-read: step 20 transition: 'resized p before 19 after 213'. So in the frame after RIGHT #1, there were 213 purple pixels. Then in step 21, p went back to 21. So there was a transient purple overlay in the frame at step 20 — but wait, the frame at step 20 is a real history frame, and it shows p=213. That's odd. Unless the frame captured mid-animation (the animation's intermediate frame got stored).
Hmm, actually more likely: the RIGHT action's animation includes a "flash" where a region turns purple? Hmm.
But more importantly: at step 20, S went 2056 → 1823, and at step 21, S 1823 → 1056 with 189 green pixels appearing. And at step 20, the B background changed a lot ("appeared B 1858 at [0,0] bbox 0,0,61,63"), and lots of G dots appearing/disappearing at rows 58-62.
Hmm, this suggests the whole board is SHIFTING! Like the maze scrolls vertically! Look: at step 20, G dots disappeared at rows 58,59 and appeared at rows 62 →

**Pensamiento:**

WOW. The board has completely changed! This is NOT a shift of the previous board. It's a different maze:
- Rows 1-11: sky cols 13-53 (top room)
- Rows 12-18: sky cols 13-23, black cols 24-42 (with 3 bricks at cols 25-41), sky cols 43-53
- Rows 19-29: sky cols 13-53 (middle room)
- Row 30: all black
- Rows 31-35: bricks at cols 13-29 (3 bricks), rest black
- Row 36: all black
- Rows 37-41: bricks at cols 13-29, sky cols 31-48ish, sprite at cols 49-53
- Row 42: sky cols 31-53
- Rows 43-47: sky cols 13-53
- Rows 48-60: sky cols 31-53 (with black at cols 13-30)
- Rows 61-62: sky cols 13-53
- Row 63: purple bar 22 + white 42
Hmm, this looks like a completely different level layout! Did the level change? current_frame.level — let me check. Maybe the level advanced (level 2) without reporting level_completed? Hmm, the results said level_completed False.
Wait, maybe the game is a "scrolling" game where the maze is regenerated? Or maybe... hmm.
Actually hold on! Maybe the maze is a "pipe" that is being rearranged: the level might be a "conveyor" where the whole maze shifts. Let me compare the step-19 board (before the RIGHTs) with the current one.
Step 19 board (after clearing all bricks):
- Top-right room rows 0-11 cols 31-53, plus the freed top-left rows 1-5 cols 13-29 and rows 6-11? Hmm, I don't have the full step-19 board. Let me RLE the step-19 frame and compare.
Hmm, let me think about the purple thing: at step 20 the frame had p=213 pixels. That's a big purple overlay — maybe a

**Pensamiento:**

Still level 1. And p is only on row 63 (22 pixels). So at step 20 the frame had 213 purple pixels — that must have been an animation frame captured (the harness stores the final animation frame... hmm, but it says history[i].frame is the frame after the action).
Hmm, 213 purple pixels at step 20. And 1858 black pixels "appeared" at [0,0] bbox 0,0,61,63. Hmm.
Wait. Maybe the purple flash covered the whole board (a "screen wipe") and the board at step 20 was mid-transition: the maze was being replaced! The step-20 frame had p=213 (a purple overlay pattern?) and the new maze appearing.
So the maze REGENERATED at step 20-21. Why? Because... hmm, maybe because I cleared all the bricks! Clearing all bricks = the level's goal, and then the level "advances" by generating a new maze... but level stays 1 and level_completed=False.
Hmm! Maybe this is an infinite/procedural game where the goal is to clear all the green bricks, and when cleared, a new maze is generated (a new "wave")? But then the level would never complete...
Or maybe the purple flash was a "score/celebration" and the maze regenerated as a new sub-level. Hmm.
Alternatively: maybe the maze is regenerated every N steps? Let's check when the maze changed: step 19→20 (sky 2056→1823, p=213) and step 20→21 (bricks appeared, sky → 1056). So the change happened over steps 20-21.
Wait, maybe the frame at step 20 was the animation frame with a purple "wipe" and the new layout. Let me look at the step-20 frame's RLE to understand t

**Pensamiento:**

Now I see the step-20 frame: it's a DIFFERENT maze (the sprite at cols 24-28, rows 37-41). And purple pixels at rows 59-63 in a diagonal dot pattern — that's the purple dot pattern (the wall texture turned purple?) at the bottom rows. Hmm, that's the "p" 213 pixels = purple dots in the black region at rows 59-63. Interesting: the purple dots appear in the wall texture at the bottom.
So at step 20, the maze was ALREADY different from the original (the layout with rooms at rows 0-5, 6-18, 19-29, shaft at 30-36 cols 43-47, bottom room rows 37-62 cols 31-53...).
Wait, in the step-20 frame: rows 0-5: sky cols 13-53; rows 6-18: sky cols 31-53; rows 19-29: sky cols 13-53; row 30-36: black with a shaft at cols 43-47; rows 37-41: sky cols 13-36 and 39-50 with the sprite at cols 24-28...; rows 43-47 sky cols 13-53; rows 48-60: sky cols 31-53; rows 61-62: sky cols 13-53.
Hmm, so the maze at step 20 is a completely different layout from the original. And the sprite was at cols 24-28 (not 37-41 as I expected from 31+6=37). Hmm! The sprite's position at step 20: row 37 has 'b' at col 25? Let me parse: row 37: "B2 G1 B5 G1 B4 S24 B2 b1 B2 S12..." → positions: col0-1 B, col2 G, col3-7 B, col8 G, col9-12 B, cols13-36 S (24), cols37-38 B, col39 b, cols40-41 B, cols42-53 S. Hmm, so the sprite's blue is at col 39 in row 37 → the sprite halo is at cols 37-41. So the sprite is at L=37 ✓ (consistent with 31+6).
OK so the maze regenerated at step 20 (after my first RIGHT post-clearing). And the spri

**Pensamiento:**

All bricks cleared again (green 0), no win. Now let's see if the maze regenerates. Let me wait a step or two (press LEFT/RIGHT or just do nothing?). Any action costs a step. Let me press RIGHT (or LEFT) once and check whether the maze regenerates (like last time it regenerated right after clearing).
Actually last time: cleared at step 19, then RIGHT at step 20 → maze regenerated. So the regeneration happened on the NEXT action after clearing. Let me press LEFT now and see.
Hmm, but wait. Let me reconsider: maybe the maze regenerates every 20 steps regardless (step 20 = regeneration). If so, the next is step 40. We're at 32. Pressing LEFT → 33. If the maze changes at 33, it's clear-triggered.
Let me press LEFT and check.

before = counts(current_frame)
r = action(['LEFT'])
after = counts(current_frame)
d = frame_diff()
print('step', current_frame.step, 'sky', before[1], '->', after[1], 'changed', d['changed_cell_count'], 'done', r['level_completed'])

**Pensamiento:**

No maze regeneration after clearing (step 32, sky unchanged 2117). So the regeneration at step 20 was NOT triggered by clearing... OR it was triggered but with a delay, or it's time-based (every 20 steps).
Hmm wait, actually let me reconsider. Maybe the regeneration was triggered by clearing all bricks but occurred at the NEXT action... which is what happened (cleared at step 19, regenerated at step 20). Now cleared at step 31, next action at step 32 = LEFT → no regeneration. Hmm! Contradiction.
Unless the regeneration is time/step-based every 20 steps: step 20 → next at step 40.
Let me test: press LEFT/RIGHT a few times to reach step 40 and see if the maze regenerates. That's ~7 actions. Hmm, but if the maze regenerates on a timer, the game is about clearing bricks before... hmm.
Alternatively, maybe the maze regenerates when the sprite's "hole" moves... no.
Hmm, let me think about the step-20 regeneration differently. What if the maze didn't regenerate but rather the WALLS shifted? Let me carefully compare the step-19 and step-20 layouts. Let me get the step-19 RLE (history[-5] or so). Actually, at step 19 the layout was the ORIGINAL maze (with all bricks cleared):
Original: rows 0-11 sky cols 31-53 (top-right room); rows 1-5 cols 13-29 sky (freed top-left bricks); rows 6-11: cols 13-30 black; rows 12-18: cols 31-35 sky (freed), 36-53 black... wait no, the bricks at rows 13-17 cols 37-53 were also freed, so rows 12-18 cols 31-53 sky?

Current maze (step 33):
- rows 1-29: sky cols 13-53 (one big room)
- rows 30-36: sky cols 13-29 (the freed bricks area), black elsewhere
- rows 37-41: sky cols 13-42 (sprite at 43-47), then sky 44-49? Let me parse row 38: "B13 S30 B1 Y1 b2 B1 S6 B10" → cols 13-42 S (30), col43 B, col44 Y, cols45-46 b, col47 B, cols48-53 S (6)... hmm "S6 B10" → cols 48-53 S. So row 38: sky 13-42, sprite 43-47, sky 48-53.
- rows 42-47: sky 13-53
- rows 48-60: sky 31-53
- rows 61-62: sky 13-53
- bar = 32 (step 33 → 32 purple pixels; so bar = step - 1).
So the maze is now: a big top room, a middle band, etc. The sprite is at cols 43-47, rows 37-41, in an open area.
Hmm, the sprite is at the same rows as before (37-41). It's in a wide open region. If buoyancy were a thing, the sprite would rise through the open sky above (rows 30-36 at cols 43-47: row 30-36 cols 43-47 are black per "B34" after S17 → cols 30-63 black). Hmm, row 30: "B13 S17 B34" → cols 13-29 S, cols 30-63 B. So above the sprite (cols 43-47) is black at rows 30-36. Blocked again! Interesting — the sprite is ALWAYS right under a ceiling at rows 30-36.
Hmm, that's suspicious. The sprite sits at rows 37-41 in every maze, right below a wall band at rows 30-36. In the original maze the band was rows 30-36 with a shaft at 41-45. In the current maze, the band is rows 30-36 with an opening at cols 13-29 (where the bricks were).
So the sprite needs to move LEFT to cols 13-17 (or wherever within 13-29) to have an opening above... and then may

**Pensamiento:**

MAJOR new information! The current frame shows:
- A new maze with a PINK object (a plus shape, pink with black outline) at rows ~18-22, cols ~19-23 — that's a new object! It looks like the same sprite shape but PINK.
- 3 green bricks at rows ~28-32, cols 31-47.
- The blue sprite at rows ~34-38, cols 25-29.
- Sky rooms.
And the last action animated 39 frames with 2514 transient cells — the maze regenerated during that animation!
So the maze regenerates (periodically?), and now there's a PINK sprite — maybe a second player/enemy or a "goal" object!
The pink object is at rows 18-22 cols 19-23 (in the upper room), and the blue sprite is at rows 34-38 cols 25-29 (in the lower room).
So the level may have a "target" object (pink). Hmm, or the pink is another rocket that moves on its own.
Wait, maybe the pink is the sprite's "goal" — like "reach the pink". Or maybe the pink is a second player.
Hmm, the maze regenerated again (this is the 2nd regeneration). Let me check when regenerations happen: step 20, step 36? Hmm, at step 32 (LEFT) no regen; steps 33,34,35 LEFT LEFT LEFT — the regen happened during the last one (step 35/36). The animation had 39 frames — a big regeneration animation.
So the regenerations: step 20 and step 35/36. Hmm, 15-16 steps apart. Or maybe the regen is triggered by something else.
Let me look at the animation timeline for the last action to see the sequence of the regeneration.
Also note: the pink object appeared. Maybe the pink object is a "goal" that appe

**Pensamiento:**

EXCELLENT! Steps 4-14 show the sprite moving UP by 2 rows per frame at cols 25-29! The sprite ROSE! So buoyancy/vertical movement IS real: the sprite moved up from rows 36-41 to rows 14-21 and beyond. It rose through the open sky above (the freed area at cols 13-29 rows 30-36).
So the sprite DOES float upward automatically! Then why didn't it rise earlier? Because there was no opening above. Now at L=25 with an opening above (cols 25-29 rows 30-36 sky), the sprite rose!
Wait, but it rose through the whole upper room? Let me see the later steps of the timeline. And the current frame shows the sprite at rows 34-38 cols 25-29 and a PINK object at rows 18-22 cols 19-23. Hmm! So the sprite rose... and then the maze regenerated, and now the sprite is at rows 34-38?
Let me see the rest of the timeline (steps 15-39).

**Pensamiento:**

Steps 22-30+: the maze is regenerating (lots of changes), and at step 29-30 a P (pink) appears: 'B>P': 3, 'S>P': 1. So the pink object appears during the regeneration.
So the sprite rose to the top (rows 1-7 at step 21) and then at step 22 the maze regenerated (a new wave), and the sprite... In the current frame, the blue sprite is at rows 34-38 cols 25-29, and there's a pink object at rows 18-22 cols 19-23.
So after the maze regenerates, the blue sprite is placed in the new maze (at the bottom area) and a PINK sprite appears in the upper area. The pink might be a "ghost" of where the sprite reached? Or a new entity (enemy/goal).
Hmm, maybe the pink is the "goal" the sprite must reach! In the current frame the pink is at rows 18-22 cols 19-23 in the upper room, and the blue sprite is in the lower room at rows 34-38 cols 25-29. They're in different rooms.
Hmm, or maybe the pink object is a "flag" marker showing where the sprite must go.
So the goal is likely: get the blue sprite to the pink object's location (or the pink marks the goal). And the sprite floats UP automatically when there's an opening above, and moves horizontally 6 cells per press. The maze regenerates periodically (each wave).
Hmm, wait. Let me reconsider: maybe the pink appears at the position the sprite reached at the end of the previous wave (the top). Hmm.
Let me now examine the current frame carefully: the pink object's shape (a plus, like the sprite's blue body) with a black outline. It's the same shape

**Pensamiento:**

Now I see:
- The pink object is a PLUS shape (5 pixels: rows 19-21, cols 20-22) — that's a 3x3 plus (5 cells), NOT the same as the blue sprite (6 cells). It's a pink plus/cross marker. This is likely the GOAL/TARGET marker!
- It's at rows 19-21, cols 20-22, inside the upper room (rows 19-29, cols 13-53).
- The blue sprite is at rows 37-41, cols 25-29 (bbox), in the lower room (rows 37-62).
- 3 green bricks at rows 31-35, cols 31-47.
- The upper room (rows 19-29) and lower room (rows 37-62) are separated by the wall band rows 30-36, which is solid black except... row 32-34 cols 31-35, 37-41, 43-47 have bricks (N). So the band rows 30-36 contains 3 bricks at cols 31-47. If I destroy those bricks, the band becomes open at those columns → the sprite can rise through!
So the puzzle is: destroy bricks to open paths, and the sprite floats up; get the sprite to reach the pink marker!
Hmm, but how does the sprite reach the pink? The pink is inside the upper room at rows 19-21 cols 20-22. The sprite rises to the top of the upper room (rows 1-5?) — hmm, the upper room is rows 19-29 only (433 px). Above it (rows 0-18) is black. So the sprite would rise to rows 19-23 in the upper room... and the pink is at rows 19-21 cols 20-22.
So the sprite must rise through an opening in the band and then be at the pink's column. The sprite rises at its current column. The pink is at cols 20-22. The sprite's reachable columns: L ∈ {13,19,25,...} → the sprite's halo would be at 19-23, i.e., blue at 21-2

The sprite rose into the upper room and is now at rows ~37-41... wait, the sprite_cells output shows blue at rows 37-40 cols 32-33, yellow at 34. Hmm, but the image shows the sprite in the upper room next to the pink marker!
Oh I see — the maze layout changed! The current frame shows:
- Upper room at rows ~37-47 (sky), containing the pink plus at cols ~20-22 and the blue sprite at cols ~31-35.
- Below: a wall band with 2 green bricks at cols ~37-47.
- Bottom room rows ~55-62.
So the whole maze shifted DOWN?! The rooms are now in the lower part of the board. Interesting: the maze scrolls down over time!
Hmm, the current image: rows 0-36 are all black (wall). The upper room is rows 37-47. Then a band rows 48-54 with 2 bricks. Then a bottom room rows 55-62.
So the maze shifted down by ~18 rows? Or the maze regenerated again.
And the sprite is in the upper room at cols 31-35 (L=31), rows 37-41, next to the pink at cols 19-23, rows 37-41.
The sprite is directly to the RIGHT of the pink! One LEFT press = 6 cells left → the sprite would land exactly on the pink (pink at cols 19-23, sprite at 31-35 → 31-6=25, not 19). Hmm, one LEFT would put the sprite at cols 25-29, which is adjacent to the pink (pink 19-23). Two LEFTs → 19-23 = exactly the pink's position!
Let me press LEFT once and see: does the sprite stop at 25-29 (adjacent), or does it get blocked by the pink, or does the pink disappear (collected)?
Let me press LEFT and observe.

```python
r = action(['LEFT'])
print('gp', r['gameplay_changed'], 'done', r['level_completed'], 'over', r['game_over'], 'anim', (r.get('animation') or {}).get('frames'))

The sprite moved LEFT to halo cols 25-29 (blue at 27-28, yellow at 26). The pink is at cols 20-22 (boundary [37,21],[38,22] → bbox rows 37-41? hmm, P pixels at rows 37-41? Let me see: P boundary[:2] = [37,21],[38,22] → the pink plus is at rows 37-41? no, the pink is a 3x3 plus: rows 37-39? Hmm, earlier the pink was at rows 19-21 cols 20-22 (3 rows). Now the pink bbox top-left is (37,21)... hmm, that's the plus's top cell at (37,21), so the plus spans rows 37-39? Hmm, the boundary list starts at the topmost-leftmost. Let me not worry.
The sprite is now at halo 25-29, and the pink at 20-22. One more LEFT → halo 19-23 → overlapping the pink. Let's try. If the pink is a goal, touching it should win.
Let me press LEFT.

**Pensamiento:**

LEVEL 1 COMPLETE! The goal was: get the blue sprite (which floats up when there's an opening above) to touch the pink plus marker. Tools: LEFT/RIGHT move 6 cells horizontally; MOUSE destroys green bricks (turning them into sky).
Now level 2. New elements: purple/pink-purple objects with yellow bottoms at the top-left (3 of them at rows ~7-12), and 2 rows of green bricks (7 per row).
Let me inspect the new board.
Mechanics recap:
- Sprite: 5x5 halo, moves 6 cells per horizontal press, blocked by walls; floats up through openings until it hits a ceiling.
- Green bricks: clickable → become sky.
- Goal: reach the pink plus marker (the "target").
- Timer bar at bottom row: 1 pixel per step, game over at 64.
Level 2 has purple objects with yellow bases — new mechanic. Let me inspect.

**Pensamiento:**

Level 2 layout:
- Top-left: 3 purple objects (12 px each, 3x4) at rows 7-10, cols 14-16, 20-22, 26-28, each with a yellow row at row 11 (YWY pattern: yellow-white-yellow). These look like "candles"/"torches"? Or "keys"? They're purple with a yellow base.
- A small sky room rows 13-23, cols 13-29 (199 px).
- A big sky room rows 0-23, cols 37-53 (408 px).
- Two rows of green bricks: rows 25-29 and 31-35, each 7 bricks (cols 13-53).
- Bottom big room rows 37-62 cols 13-53.
- The sprite at rows 37-41, cols 19-23 (facing right, blue at 20-21, yellow at 22).
- No pink marker visible! Hmm. So where's the goal? Maybe the goal is the purple objects (which might turn into the pink marker when something happens)?
- The bar shows 36 purple pixels — hmm, that's the step counter carried over from level 1? Step 40, bar 36 = step - 4? Hmm, at level 2 start the bar should reset. Let me check: bar 36 at step 40 → bar = step - 4. So the bar didn't reset with the level; it's a global step counter (or a "lives" bar that decrements). Hmm, at step 39 the bar was ~38? Let me not worry; it's the timer. Actually it might be a global timer for the whole game! If it hits 64 → game over. That's concerning: we have ~26 steps left for the entire remaining game!
Hmm, wait. Let me check the bar's behavior across the level transition. Let me look at the last few history frames' bar counts.
Also: no pink marker on this level. Maybe the purple objects are the goal (the sprite must reach them), or maybe they're

**Pensamiento:**

Confirmed: rows 24, 30, 36 are solid black walls. So there's NO vertical path through the brick band — the sprite cannot rise from the bottom room by removing bricks only.
Hmm! So how do we progress? Options:
(a) The maze regenerates periodically (as in level 1) and new layouts may provide paths.
(b) The purple objects are involved (maybe they can be "collected" by clicking, or they're the goal).
(c) Clicking a brick does something different in level 2 (e.g., destroys the wall rows too).
Let me check the level-1 maze regenerations: they happened at steps 20 and 36 (and maybe at the level start). Hmm, in level 1, the initial maze was the original; at step 20 it regenerated; at step ~36 it regenerated again. The intervals: 20, 16. Hmm.
Maybe the maze regenerates every ~16-20 steps. If the level's step counter resets at level 2, the regeneration might come at level-step 20.
Let me look for a more reliable trigger. In level 1: the regeneration at step 20 happened right after I cleared all bricks (step 19). The second regeneration at step 36 happened right after I moved to cols 25-29 where there was an opening (the sprite rose to the top and then the maze regenerated!). Hmm! Interesting: in the animation, the sprite rose to the top (rows 1-7) and THEN the maze regenerated (steps 22-38 of that animation).
So maybe the maze regenerates when the sprite reaches the TOP of the maze (row 0-5?) — i.e., the sprite "escapes" and a new maze appears!
And the first regeneration at step 20: hm

**Pensamiento:**

Clicking the purple object = no-op. So purple objects aren't clickable.
Note the bar: it's now 1 pixel again (the image shows just 1 purple pixel at bottom-left). So the bar RESET at the level change. Good — the budget is per level (64 steps). We're at step 41 in env terms, but the level-local step count is small.
So level 2: the sprite is in the bottom room; the brick band rows 25-35 is backed by solid walls at rows 24, 30, 36. No vertical escape.
Hmm! Unless the sprite's rise requires only ONE row of bricks removed... no, rows 30 and 36 are solid.
Wait... maybe I should reconsider: maybe the sprite doesn't need to rise. Maybe the goal is different in level 2. The purple objects with yellow bases... maybe they're "goals" that the sprite must touch — but they're in the wall (rows 7-11). Hmm, the sprite can't get there.
Unless: the purple objects can be moved/affected. Or maybe they're "torches" that light up.
Hmm, let me reconsider the maze. The sprite is in the bottom room (rows 37-62). The two upper rooms: rows 13-23 cols 13-29 (small) and rows 0-23 cols 37-53 (big). The purple objects are above the small room.
Hmm, what if the maze regenerates (as in level 1) and the new maze will have a path? The key question is what triggers regeneration.
Let me re-examine the level-1 regeneration triggers more carefully:
- Regen #1 at step 20: right after clearing all bricks at step 19, on the next action (RIGHT).
- Regen #2 at step 36: during the action where the sprite rose to the top

**Pensamiento:**

Key data from the animation bboxes:
- Step 20 (RIGHT): bbox [37,1,62,62] frames 4 → the maze changed (rows 37-62 + full width) — regen #1 started.
- Step 21 (RIGHT): bbox [0,1,62,62] frames 44 → big regen animation.
- Step 35 (LEFT): bbox [0,1,62,62] frames 39 → regen #2 (sprite rose + regen).
- Step 37 (RIGHT): bbox [0,1,62,62] frames 22 → regen #3! (when I clicked a brick then moved RIGHT, the sprite rose into the upper room).
So regenerations happened at steps 20/21, 35, 37. Intervals: 20→35 = 15, 35→37 = 2! So it's not a fixed timer.
Hmm, regen at 37: that was the RIGHT move where the sprite rose through the opened brick hole into the upper room and landed next to the pink. And regen at 35: the LEFT where the sprite rose to the top.
Hmm, so maybe the "maze regeneration" is actually the maze SCROLLING DOWNWARD! I.e., when the sprite rises to the top of the current maze, the maze scrolls down and new content appears at the top — like a vertical scrolling game!
Let's check: at step 35, the sprite rose to rows 1-7 (top) and then the board "shifted" — and the sprite ended at rows 34-38 (a shift of +33 rows? hmm).
Hmm, that doesn't look like a scroll.
Alternatively, each time the sprite reaches the top area, a new "wave"/maze is generated (the sprite is reset to the lower room).
Hmm, but at step 37 the sprite only rose from the bottom room into the upper room (rows 37-41 → 37-41 in a shifted maze?). Hmm.
Actually, maybe the maze doesn't regenerate at all — maybe the maze SCROLL

**Pensamiento:**

Confirmed: rows 24, 30, 36 are entirely black (no gaps). So the brick band is impassable — the sprite cannot leave the bottom room in level 2's initial layout.
Therefore the maze MUST change. Given the camera/scroll hypothesis, maybe the maze scrolls DOWN over time (gravity: the maze descends toward the sprite?), i.e., the sprite stays and the maze moves. In level 1, at step 20-21, the maze changed while the sprite stayed at rows 37-41.
Under the "scroll" model: the maze scrolls down by some amount each step? Let me test: in level 1, from step 19 to 20 the sky went 2056 → 1823 and the layout changed drastically. If the maze scrolled by 6 rows per step, the sprite (fixed at rows 37-41) would encounter different content.
Let me test the scroll hypothesis on level 2's frames: I'll do a harmless action (LEFT then RIGHT, or just LEFT) and check if the maze content shifts vertically by a constant amount.
Actually, a cheaper test: press LEFT (the sprite is at cols 19-23; LEFT → cols 13-17, the leftmost? The bottom room spans cols 13-53, so LEFT moves it to L=13). Then compare the frames: if the maze scrolled, the walls would shift.
Let me do LEFT and diff.

```python
before = current_frame
r = action(['LEFT'])
after = current_frame
d = frame_diff(before, after)
print('changed', d['changed_cell_count'], 'sprite', sprite_cells(after))

**Pensamiento:**

No scroll: shift 0 has 98.5% match (only the sprite moved). So the maze is static in level 2 for now.
So level 2's maze is static and the bottom room is sealed. The sprite can't escape by clicking bricks. So the level must be solvable another way. Options:
1. The maze regenerates on a timer (we've seen 1 step pass; need to wait).
2. Something else happens when the sprite does something.
Wait... let me reconsider. Maybe the sprite doesn't rise via the brick band. Maybe the sprite can move through the brick band by destroying bricks AND the black rows 30/36/24 are actually not walls but... they ARE black like the outer wall.
Hmm, hold on. What if the sprite doesn't need to go up? What if the level's goal is at the bottom? The bottom room spans rows 37-62 and row 62 is the last row... row 63 is the HUD. Hmm, the bottom room touches the bottom edge? Row 62 has sky at cols 13-36 (from the check above, truncated at 24 entries). Let me check row 62 fully: it printed cols 13-36 (cut off at 24 entries). Probably sky 13-53.
Hmm.
OK here's another thought: maybe the maze regenerates when the sprite has been in the same "room" for a while...
Let me reconsider the level-1 regenerations with the new "camera" insight. Actually, maybe there was NO regeneration in level 1 — maybe the maze SCROLLED. Let me test that properly with the level-1 data: compare the frames at steps 19 and 21 with a vertical shift. Earlier I compared layouts by eye and concluded "regenerated". Let me test the shift hy

34 vs 36 [(0.953, 40, 943), (0.95, 39, 984), (0.947, 38, 1025), (0.945, 37, 1066)]
```

**Pensamiento:**

Interesting! For 34 vs 36: the best match is shift +40 with 95.3% — but that's suspicious because a large shift means fewer overlapping rows (943 cells) and the board is mostly uniform sky/black rooms, so a high match rate is easy to get by chance with big uniform regions. Hmm, 95% is quite high though.
For 19 vs 22: best is -36 with 83% — not conclusive.
The uniformity of the board (large sky regions) makes this test weak. Let me instead check a distinctive feature: the G-dot lattice. The G dots have a specific periodic pattern; a shift by a multiple of the period would match trivially. Hmm.
Better: track the maze's room boundaries. Ugh.
Let me step back and think about the game design differently.
Alternative interpretation: maybe the game is not about the sprite climbing at all. Maybe it's about the green bricks: the goal might be to clear all the bricks (in level 1, the level completed when the sprite touched the pink marker... hmm, no, that was definitive: level_completed fired when the sprite overlapped the pink).
OK so the goal is: touch the pink marker. In level 2, there's no pink marker visible. So the pink marker must appear later (as in level 1, where the pink appeared after a maze change at step 35-36).
In level 1, the pink marker appeared in the regenerated maze at step 36 (the animation step 29-30 showed P appearing). And it appeared right next to where the sprite would end up.
So maybe the pink marker appears after a "maze regeneration" event, and the level's r

**Pensamiento:**

GAME OVER on level 2! Let me diagnose:
- The death frame shows a COMPLETELY DIFFERENT maze (the maze regenerated!) with the sprite at rows ~41-45 cols 13-17, purple objects at rows ~24-28, bricks in new places. And the bar in the death frame: looking at the bottom-left of the death image, there's a purple bar of about 90 pixels wide out of 64? Hmm, the death image shows a purple bar from col 0 to ~col 90 (in the 640px image, each cell is 10px, so the purple bar spans ~0-90px = cols 0-9). So the bar had ~9 pixels → NOT depleted... wait, the bar GROWS each step (in level 1 it grew 1/step from 1). Hmm, in level 1 the bar grew from 19 to 38 over steps 19-38. So the bar is a GROWING bar. If the bar is a "steps used" bar, then death occurs when the bar reaches 64 (full). In the death frame the bar was ~9-10 → not full.
Hmm, wait. Let me re-read the bar rule: "the bar shrinking with each action is NORMAL". In our game the bar GROWS each action (purple pixels added at the left, replacing white). Hmm, actually maybe the bar is a REMAINING budget bar that shrinks from the right: white = remaining, purple = used. As purple grows, white shrinks. When white is gone → out of budget. In the death frame, the purple bar was ~9 wide and white ~55 → plenty remaining. So the death was NOT budget-related.
So the fatal action itself (MOUSE at (33,15), clicking the second-row brick at cols 13-17) caused the death!
Why? Look at the death frame: the maze regenerated during that click (1996 transient

**Pensamiento:**

Interesting! In the death frame:
- The bar is 46 (pre was 45) → not depleted (54 white remain). So the death was caused by the action itself.
- The death frame has NO blue sprite! sprite_cells(death) found only Y at row 35 (the purple objects' yellow bases). So the sprite DISAPPEARED → death = the sprite got crushed/removed!
So when I clicked the brick at (33,15), the maze regenerated (or something) and the sprite was destroyed.
Let me look at the animation timeline to see what happened: 33 frames, 1996 transient cells. Let me see the first steps and where the sprite went.
The pre-death frame (step 48): the maze had the top brick row cleared (7 bricks gone), the bottom row intact. The sprite was at cols 13-17 rows 37-41 (below the brick at rows 31-35 cols 13-17 which I then clicked).
So: the sprite was in the bottom room directly below a brick. I clicked that brick → the maze regenerated → the sprite was crushed → death.
Hmm, why did the maze regenerate at that moment? Maybe because clearing that brick opened a path directly above the sprite and the sprite rose... and then the maze regenerated (as in level 1: when the sprite rises to the top, the maze regenerates)? But the sprite died...
Hmm, let me look at the timeline to understand. Let me print the first ~12 steps and the last few steps of the fatal animation.

```python
tl = last_animation_timeline
print('frames', tl['frames'], 'steps', len(tl['steps']))
for s in tl['steps'][:10]:
    print(s['step'], s['changed'], s['bbox'], str(s.get('changes') or s.get('transitions'))[:130])

for s in tl['steps'][-6:]:
    print(s['step'], s['changed'], s['bbox'], str(s.get('changes') or s.get('transitions'))[:130])

**Pensamiento:**

Now I understand the fatal sequence:
- Steps 1-4: the brick at rows 31-35 cols 13-17 was destroyed → became sky (also row 30 cols 13-17 became S and row 36 cols 13,17 became S — so the wall rows 30/36 at that column also opened! Interesting: destroying a brick ALSO opens the adjacent wall rows?! Look at step 1: 'B>S @ (30,13)...(30,17), (36,13),(36,17)' — so when a brick is destroyed, the cells above and below it (in the wall rows) also become sky! Hmm, partially: (36,13) and (36,17) but not (36,14-16)? Hmm, and (30,13)-(30,17) all 5.
Hmm, that's the "brick destruction" animation: the brick's frame (dark gray G outline) turns to sky too. The G cells are the brick's border, which extends into rows 30/36? Wait, the bricks are 5x5 with a 1-cell dark-gray border: rows 25-29 for the top row... hmm. Let me re-check: the N nodes had bbox rows 25-29 (the green 5x5 minus border?). Actually the segmentation said N 21 pixels with bbox rows 25-29 cols 13-17 → 21 = 5x5 minus 4 corners = 21 ✓. So the green core is a plus-ish shape (5x5 minus corners) and the G (dark gray) border cells are at the corners and edges? Hmm.
Anyway: destroying a brick opens a hole in the wall rows too! That means the brick band IS passable after destroying a brick — the wall rows 30 and 36 (and 24) at that column become sky!
So in level 2, destroying a brick at rows 31-35 cols 13-17 opened a path: rows 30-36 became sky at cols 13-17 (at least partially).
- Steps 5-10+: the sprite ROSE through that hole (rows 34→

**Pensamiento:**

Now I understand the death:
- The sprite rose through the hole created by destroying the brick at rows 31-35 cols 13-17 (destroying a brick also opens the wall rows above/below it).
- The sprite rose at cols 13-17 and at frames 8-9 it shrank (6→5→1 blue cells) → CRUSHED! At frame 8-9 the sprite was at rows ~28-32 and got squashed. Why? Because the sprite rose into a 1-wide passage? Hmm.
Let me look: the sprite rose at cols 13-17 (halo). Above the brick row (rows 25-29) there was still a brick at rows 25-29 cols 13-17 (I had only cleared the top row bricks at cols 15,21,...,51 → wait, I DID clear the top row brick at cols 13-17 (click (27,15))). Hmm, so both rows were open at cols 13-17.
Frame 7: b at (30,15) len 6; frame 8: len 5; frame 9: len 1; frame 10: gone.
So the sprite was destroyed while rising at rows ~26-32. What killed it? The purple objects are at rows 7-11 (in the pre-death maze) — no.
Hmm, what was above? The small room rows 13-23 cols 13-29. The sprite at cols 13-17 rising... it would enter the small room at row 13. Hmm, but the sprite died around rows 26-32.
Wait, maybe the sprite was crushed because the hole was only 5 wide (cols 13-17) but the sprite's halo is 5 wide — it fits exactly. But the walls at cols 12 and 18... the hole is at cols 13-17 exactly = the halo width. Hmm, so it should fit.
Unless the hole wasn't full width: from the timeline step 1: 'B>S @ (30,13)...(30,17)' ✓ 5 cells; '(36,13),(36,17)' only 2 cells at row 36! And step 3: 'B>S @ (32,14).

**Pensamiento:**

Now I see clearly what happened. The maze is SCROLLING DOWNWARD! Look at frames 6→10: the structure (the hole with the sprite inside, 5 wide at cols 13-17) moves DOWN the screen while the sprite stays around rows 26-30. Wait, no: the sprite's halo pattern 'BBBbBB/Ybb/Ybb/BBbBB' moves from rows 32-35 (frame 6) to rows 24-28 (frame 10) — the sprite is moving UP relative to the screen... and the maze structure (the S column at cols 13-17 and the bricks at cols 19+) — in frame 6, the S column at cols 13-17 extends from rows 24-29 and the wall 'BBBB' at row 30 cols 18-22; in frame 10 the S column at cols 13-17 is at rows 30-35.
Hmm, so the maze features moved DOWN while the sprite moved UP. That means the maze scrolls down at ~1 row/frame while the sprite rises at ~1 row/frame? That's a relative speed of 2.
Hmm, actually maybe: the maze scrolls down continuously (like a conveyor) and the sprite rises. In frame 10, the sprite's halo is at rows 24-28, and the maze's hole (S column) is at cols 13-17 rows 30-35 — so the sprite has left the hole and is inside the "small room" region.
Then at frame 10 the sprite's blue cells vanish (len 0). Hmm, but the sprite's halo is still visible at rows 24-28 in frame 10 (the 'b' pattern). Oh wait, sprite_cells looks for 'b' (blue) — in frame 10 there are no 'b' cells?! But the printed crop shows 'b' at rows 25,26,27,28 (e.g., 'BBBBbBB' at row 25). Hmm, sprite_cells(fr) uses... let me check my retained definition. It probably searches for 'b' and '

**Pensamiento:**

So the sprite rose steadily (rows 37→13) and at frame 19 it was at rows 13-16 with only 2 blue cells, then at frame 20 it DISAPPEARED → crushed/killed.
The sprite reached row 13-16 at cols 15-16. The small room is rows 13-23 cols 13-29. Above the small room is row 12 (the ceiling with 1-wide gaps at cols 18,24).
Hmm, so the sprite at rows 13-16 was inside the small room (fine), then at frame 19-20 it got crushed. Why?
The maze was scrolling DOWN. So the ceiling row 12 (solid black except gaps) moved DOWN onto the sprite! Because the maze scrolls down continuously, the sprite must keep rising or be crushed.
So the sprite was rising at ~1 row/frame and the maze was scrolling down at ~1 row/frame? Then the sprite's screen position should have stayed roughly constant... but the sprite moved up the screen from row 37 to row 13 while the maze scrolled down. Hmm.
Let me reconsider: maybe the maze did NOT scroll. Let me look at the frames again: in frame 6, at cols 13-17, rows 24-29 are S (sky), row 30 cols 18-22 = BBBB. In frame 10, cols 13-17 rows 30-35 = S. Hmm, that's the hole (the destroyed brick's column) — is it at rows 24-29 in frame 6 and rows 30-35 in frame 10? That means the hole moved DOWN by 6 rows. But the hole was created at rows 30-36 in the pre-death frame (the brick at rows 31-35 cols 13-17 + wall rows 30, 36). So in frame 6 the hole appears at rows 24-29?? Hmm, confusing. The S region at cols 13-17 in frames 6-10 could be the small room (rows 13-23) plus the hole.

Now I see the death clearly. In frame 18 the sprite is at rows 13-17 (top of the small room, right under the ceiling row 12). In frame 19 the sprite is CRUSHED: only 2 blue cells remain at rows 14-15 col 15, and the ceiling... wait, in frame 19 row 12 is "BBBBBBBSBBBB" and rows 13-16 show 'BBSSBSSSSSSS' etc. The sprite got squeezed: the halo shows S where the black... hmm, actually in frame 19 the sprite's halo appears at cols 13-17 rows 13-16 with black at col 14 and 16 (crushed by the ceiling? no...).
Look at frame 19: row 13: 'BBSSBSSSSSSS' (cols 11-22) → col 11=B,12=B,13=S,14=S,15=B,16=S,17=S... So the sprite's halo at cols 13-17 became mostly S with 'b' at col 15 rows 14,15. So the sprite was squeezed to 2 cells → then vanished in frame 20.
And crucially: the maze is scrolling DOWN! Compare frame 17 vs 18 vs 19: the purple objects moved DOWN by 1 row between frames 17 and 18? In frame 17: purple at rows 7-10, yellow at row 11, ceiling row 12, sprite at rows 14-17. In frame 18: purple at rows 7-10 (same!), sprite at rows 13-16. In frame 19: purple at rows 7-10, sprite at 13-15. Hmm, so the purple didn't move between 17-19. But in frame 21 the purple is at rows 9-12 and yellow at 13 — so the maze DID shift down by 2 between frames 19 and 21 (after the sprite died, the maze started scrolling down).
Hmm, so after the sprite died, the maze scrolled down (frames 21+), and the "death" happened at frames 19-20 when the sprite was at the ceiling.

**Pensamiento:**

The maze did NOT scroll during frames 0-20 (bricks stayed at rows 31-35, purple at rows 7-10). The sprite rose and got crushed at the small room's ceiling (row 12) → DEATH.
So: **the sprite dies if it rises into a ceiling it cannot pass** — no wait, that contradicts level 1 where it repeatedly stopped under ceilings.
Hmm, let me reconsider. Maybe the difference: in level 1, when the sprite rose, its TOP was the black halo border, which touched the ceiling. Here the same thing happened. Hmm.
Alternative hypothesis: the sprite dies when it rises into a space where it's squeezed to less than its full width... no.
Hmm, hold on. Maybe the sprite's rise is not "buoyancy" but a JETPACK that pushes up until it can, and when it's fully blocked it dies from... no.
Let me look at the level-1 case again: at step 35, the sprite rose to rows 1-7 (near the top of the board) and the maze regenerated. In level 1 the sprite's rise ended because the maze regenerated (a new maze appeared), not because it hit a ceiling. And at other times (e.g., steps 22-34), the sprite stayed at rows 37-41 under the band ceiling — it never rose into that ceiling because it never had an opening... hmm, at step 33-34 the sprite moved left with the band above it (solid) — it just stayed at rows 37-41. So the sprite never actually "pressed" against a ceiling in level 1? It did: at rows 37-41 with the ceiling at row 36 → it was resting against it (the halo's top row = 37, so the blue body's top = row 37+1=38; the hal

**Pensamiento:**

The board is the fresh level-2 start: sprite core at cols 20-22 (L=19), bricks at rows 25-29 and 31-35, and rows 0-23 at cols 37-41 are all sky (the big room) except rows 24-36 as listed.
Plan: click (27,39) and (33,39) to open the column at cols 37-41, then RIGHT ×3 to bring the sprite to L=37 → it should rise to the top.
Wait, one consideration: does destroying a brick open the wall rows above AND below? In the fatal case:
- Click (27,15) [brick rows 25-29 cols 13-17]: did it open rows 24 and 30? Let me verify from the pre-death frame (history[-3], step 48): rows 24/30 at cols 13-17. Let me check that quickly to confirm the mechanic before spending actions.
Actually, in the fatal animation frame 1, the changes at row 30 ('B>S @ (30,13)..(30,17)') happened when I clicked the LOWER brick (33,15). And the top brick click (27,15) presumably opened rows 24 and 30. So each brick click opens the wall rows immediately above and below it. Two adjacent brick rows sharing wall row 30 → clicking either opens row 30. So clicking both bricks at a column opens rows 24, 30, 36 ✓ full path.
Let me verify with the pre-death frame at step 48: rows 24 and 30 at cols 13-17 should be S (since I clicked (27,15) earlier).
Let me do that check and then execute the plan in the same call if it passes.

```python
pre = history[-3].frame  # step 48: after clearing top-row brick at cols 13-17
a = pre.ascii.split('\n')
for r in [23,24,25,29,30,31]:

**Pensamiento:**

Confirmed: clicking the top brick (rows 25-29 cols 13-17) opened row 24 AND rows 25-29 (and presumably row 30 was opened by the lower brick click). Row 30 was still black at step 48 (before the lower brick click) ✓ — so each brick click opens the wall row above and below it.
So clicking both bricks at cols 37-41 will open rows 24, 25-29, 30, 31-35, 36 → a full path from row 37 (the sprite) up to row 0 (the big room is sky rows 0-23 at cols 37-53 ✓).
Execute: MOUSE (27,39), MOUSE (33,39), RIGHT, RIGHT, RIGHT. Then inspect.
Note: the sprite's rise happens after the move that aligns it. Let me batch all 5 and inspect the result. Risk: if my model is wrong, I die and restart the level (keeping level 1). Acceptable — the alternative is slow probing.
Actually, let me be a bit careful: should I do the 3 RIGHTs in one batch? If the sprite rises at L=37, that's what I want. If for some reason an earlier position (L=25 or L=31) has an opening... no, the band is solid there.
Let me batch: 2 clicks + 3 RIGHTs.

```python
seq = [{'action':'MOUSE','row':27,'col':39},{'action':'MOUSE','row':33,'col':39},{'action':'RIGHT'},{'action':'RIGHT'},{'action':'RIGHT'}]

**Pensamiento:**

The maze regenerated (the sprite rose to the top and a new maze appeared). The sprite is now at rows ~37-41, cols 38-39 (halo 36-40?). Let me analyze the new maze.
New board (from the image):
- Top: 2 green bricks at cols ~31-35, rows 1-5 and 7-11 (a vertical pair at the top middle).
- A sky room rows ~13-29, cols 13-53, with 3 purple objects hanging at the top-right (cols ~37-53, rows 13-17).
- A brick band rows ~31-45 with gaps.
- The sprite at rows ~37-41, cols 36-40.
- A sky column at cols ~37-53 rows 43-62.
- Bottom: 3 purple objects at rows ~56-60, cols 14-28.
Interesting: now there are SIX purple objects (3 hanging at the top of the upper room, 3 at the bottom-left).
So the sprite rose to the top → new maze. Good, my model works.
Now: the goal is presumably still to reach the top (or find the pink marker). Let me analyze the new maze structure with segmentation and figure out the next rise column.
Key: I need a column where the path from the sprite's row to row 0 is clear (possibly after destroying bricks).
Let me get the segmentation and the ascii around the sprite.

```python
seg = current_frame.segmentation
for n in seg['nodes']:
    if n['pixels'] > 1 and n['color'] != 'B':
        b = n['boundary']
        print(n['id'], n['color'], n['pixels'], 'bbox', min(p[0] for p in b), max(p[0] for p in b), min(p[1] for p in b), max(p[1] for p in b))

**Pensamiento:**

New maze (level 2, wave 2). Bar = 5 (the bar reset at the start of level 2? Hmm, it shows 5 now. Earlier at step 41 the bar was 1. Level 2 started at step ~40; now step 56 → 16 steps in, bar 5? Hmm, so the bar isn't a simple step counter. Maybe the bar decreases when the maze regenerates? Or the bar is a "lives"/score bar.
Hmm, the bar in the death frame was 46 and the death was not from the bar. Now the bar is 5. So the bar might be a "progress" indicator. Let me not worry about it (it doesn't seem to be a strict timer). Actually, it might be a level-progress bar: e.g., the number of mazes cleared or the number of purple objects collected. Hmm, 5... 
Hmm, in level 1 the bar grew 1 per step. Let me check the bar at the start of level 2 (step 41: 1) and now (step 56: 5). Hmm, that's 1 per 4 steps? Or maybe the bar = the number of steps since the last maze regeneration: the regen happened at step 55 (the last action) → hmm, 1.
Hmm, whatever. Let me focus.
New maze structure:
- Big room rows 13-29, cols 13-53 (607 px) — with 3 purple objects hanging at its top-right (rows 13-16, cols 38-40, 44-46, 50-52).
- Above it: rows 1-5 and 7-11 have bricks at cols 31-35 (a vertical pair), and row 0? Let me check what's at rows 0-12 besides the bricks. The bricks at rows 1-5 and 7-11 cols 31-35. So there's a vertical brick pair at cols 31-35 above the big room (with a wall row 6 and 12 between/above).
- Brick band rows 31-35: bricks at cols 13-17, 37-41, 43-47, 49-53 (gaps at 19-35!).

Now I have the full picture of the current maze (rows 0-41 shown; let me also get rows 42-62).
Structure (cols 12-55 shown):
- Rows 1-5: brick at cols 31-35 (N with G border).
- Row 6: wall.
- Rows 7-11: brick at cols 31-35.
- Row 12: wall.
- Rows 13-17: sky cols 13-36 + purple objects at cols 38-40, 44-46, 50-52 (rows 13-17 with yellow at row 17).
- Rows 18-29: sky cols 13-51 (the big room). Note rows 13-17: sky only at cols 13-36.
- Row 30: wall.
- Row 31-35: bricks at cols 13-17, 37-41, 43-47, 49-53.
- Row 36: wall.
- Rows 37-41: bricks at cols 13-17, 19-23, 25-29, 31-35; the sprite at cols 37-41 (halo); sky cols 42-53.
- Row 41: 'BGNNNGBGNNNGBGNNNGBGNNNGBSBBBSSSS...' → hmm, row 41 col 36 = S? Let me index row 41: chars from col 12: B(12) G(13) N(14)N(15)N(16) G(17) B(18) G(19)N(20)N(21)N(22)G(23) B(24) G(25)N(26)N(27)N(28)G(29) B(30) G(31)N(32)N(33)N(34)G(35) B(36) S(37) B(38)B(39)B(40) S(41)... 
Hmm, that's the sprite's halo bottom: the sprite occupies cols 37-41 rows 37-41. In row 41, the halo's bottom-center is at col 39 → 'B'. And col 37='S', col 41='S'. Hmm, so the sprite's halo bottom row has S at its corners (the halo is a plus shape? no...).
Anyway, the sprite is at L=37 (halo 37-41) in its room (sky cols 42-53 rows 37-41 + the region below).
Wait, the sprite's halo at cols 37-41 rows 37-41 — but the cells to its left (col 36) are black, and the bricks at cols 31-35 rows 37-41. So the sprite is at the left edge of its room, in a "notch".

**Pensamiento:**

Let me be decisive with a cheap, informative probe. 
Key insight I should exploit: UNDO exists. Let me use a probe that I can undo if it's bad... but UNDO can't recover from death.
Let me think about which probe maximizes information while minimizing death risk:
Option A: Destroy the brick at (33,45) [rows 31-35, cols 43-47] and press RIGHT (sprite L=37→43) → the sprite rises into the big room and stops at rows 18-22 under the purple object at cols 44-46. Tests whether "blocked rise = death". If it survives → I can then test moving left to L=31 and rising to the top.
Given that the maze offers no other route, this is likely the intended path anyway. And note the design: the big room's upper-right has three purple objects with 1-cell gaps at cols 42 and 48 — those gaps suggest the designer wanted the sprite to be able to pass up at cols 42/48?? The sprite is 5 wide, so no.
Hmm, wait. Actually, let me reconsider whether the sprite's collision is really 5 wide. The halo is black (5x5) which matches the wall color, so I can't visually distinguish the halo from walls. What if the sprite's collision box is only the 3-wide core (yellow+blue)?
Evidence from wave 1: the sprite rose through the hole at cols 13-17 (5 wide, created by destroying a brick). If the collision were only 3 wide, the sprite could have risen through a 3-wide hole. Both models are consistent with that.
Under the 3-wide-core model, in the current maze: the sprite rising at L=37 (core cols 38-40) into the big room:

Key data:
- 19→20: 357 cells changed (partial change!), 20→21: 1024 (full regen), 21→22: 47 (just the sprite).
- 34→35: 1231 (full regen), 35→36: 36 (just the click), 36→37: 841 (full regen), 37→38: 47 (sprite).
- 48→49: 1297 (the fatal regen), 54→55: 1426 (the regen from my last RIGHT).
So regens (full-board changes) happened at steps 20-21, 35, 37, 49, 55. That's a LOT of regens — at steps 35 and 37 (2 apart) and 49, 55 (6 apart).
Hmm, so regens are frequent. What's common to all of them? Each was accompanied by a large animation. Let me reconsider: maybe the maze scrolls down by a large amount at every regen (a "wave advance"), and the wave advances whenever the sprite rises OR ... hmm, at step 20 the sprite didn't rise (I argued) but the maze changed 357 cells; then at step 21 another 1024.
Hmm, maybe at step 20 the sprite DID rise (through the shaft at cols 41-45 partially aligned with its halo at 37-41? no...).
Alternatively, maybe the maze scrolls down continuously by 1 row per step, and what I called "regen" is the accumulation. Let me test: diff between steps 21 and 22 = 47 (only the sprite) → no scroll. So no.
OK so regens happen at specific triggers. Let me tabulate what the sprite did at each regen step:
- Step 20: RIGHT (31→37). Before: all bricks cleared at step 19.
- Step 21: RIGHT (37→43) — a second big change (maybe the animation of the same regen continued into the next action).

**Pensamiento:**

The bar is exactly 1 per action, resetting at the level start and at RESET. So it's just an action counter, capped at 64. The death at step 49 (bar 10) was definitely NOT a budget death. Good — the bar is harmless (at least within 64 actions... hmm, maybe it does kill at 64? Level 1 was won at 38; level 2's death was at 10 → the death was caused by the action).
So the death at step 49 was caused by the sprite rising and being crushed. And at step 55 the sprite rose and survived (with a wave advance).
Let me now compare the two rise animations to find the difference. In step 55's animation (42 frames), let me check whether the sprite rose into the big room and whether it was ever crushed. Let me trace the sprite's position per frame in the last animation (which is now step 55's = last_animation_frames).
This is the key comparison: step 55 (survived) vs step 49 (died). Let me trace frames of the step-55 animation.

WOW! This changes everything. In step 55's animation, the sprite rose ALL THE WAY to row 0-1 (frame 18-19) — it did NOT stop at rows 18-22! It passed right through the big room, through rows 13-17 (where the purple objects and walls are!), and reached the top (row 0) — then at frame 19-20 it shrank/vanished (that's the "escape"/wave-advance animation, not death!), and then the maze regenerated and the sprite reappeared at row 0 and descended to rows 37-41 (frames 24-40) in the new maze.
So the sprite passed through rows 13-17 at cols 37-41 — where the ascii showed 'B' at col 37 and 'p' at 38-40 and 'B' at 41! That means... the sprite's rise is NOT blocked by those cells?!
Hmm! Wait. But the sprite passed through cols 38-39 (its core) at rows 13-17 — the purple object at cols 38-40 rows 13-17. So the sprite passes THROUGH purple objects and through walls??
Hmm, no wait. Let me re-derive. The sprite's blue cells are at cols 38-39 (the core is 3 wide: 38,39,40 with yellow at 40). In frames 4-18 the sprite rose from rows 34 to rows 1 continuously at cols 38-39. So it passed through rows 30-36 (the wall + brick at cols 37-41)... 
Hold on, I had already destroyed the bricks at rows 25-29 and 31-35 cols 37-41 — no wait, that was the PREVIOUS wave (wave 1, steps 51,52 clicked (27,39) and (33,39)). In wave 2 (the current maze), the segmentation showed bricks at rows 31-35 cols 37-41 (node 124) — so the maze DID have a brick there. Hmm, but the sprite rose through it at frames 4-12?!

**Pensamiento:**

HUGE revelation! Look at frame 3 (before the rise): the column at cols 37-41 is ALREADY SKY from row 0 down to row 38! Look: cols 30-45 → the crop shows 'SSSSSSSS' at cols 37-44 in every row from 0 to 22, and at rows 24-36 'BSSSSSB' → cols 37-41 = S. So the maze in frame 3 (the start of the step-55 animation) had a FULL OPEN COLUMN at cols 37-41 from row 0 to row 38!
Wait, that contradicts the current frame's ascii (which shows bricks at rows 31-35 cols 37-41 and walls at rows 0-12).
OH! I see — the frames of the animation are NOT in chronological order of what I assumed. Frame 3 shows the state right after the RIGHT action started... Hmm, but frame 3's board has a full open column and NO bricks at rows 26-34 in that column. Hmm, and the purple objects aren't visible in the crop (rows 13-17 cols 37-44 = S?).
Hmm! Actually wait. Let me reconsider: maybe these animation frames are showing the maze SCROLLING. In frame 3, at rows 24-36, cols 31-35 = 'BNNNNN' (a brick) and cols 37-41 = S, cols 42-44 = 'BNN'... 
And in the CURRENT frame (post-animation), rows 31-35 have bricks at 37-41, 43-47, 49-53 and rows 37-41 have bricks at 13-35.
In frame 3, rows 26-28 have a brick at cols 31-35 and rows 32-34 have a brick at cols 31-35. So the brick layout in frame 3 is DIFFERENT from the current frame. So frame 3 is NOT the pre-action state.
Hmm, so what is frame 3? The animation has 42 frames. Frame 0 = the pre-action state presumably. Let me check frame 0's board at rows 24-38 cols 30-46

**Pensamiento:**

Clicking a purple object = NO-OP (only the bar changed). So purple objects aren't clickable/destructible.
So: purple objects are hazards (probably), not clickable. Bricks are clickable.
Now, the key question: how to escape this maze? Let me reconsider the maze geometry. Maybe I'm wrong about the sprite needing a 5-wide halo clearance. Let me test the collision width directly with a SAFE experiment:
Experiment: destroy the brick at rows 31-35 cols 43-47 (click (33,45)) — this opens cols 43-47 at rows 30-36. Then press RIGHT (the sprite moves L=37→43) → the sprite will try to rise.
- If the collision is the 5-wide halo: the sprite rises through cols 43-47 up to row 18 (blocked by rows 13-17 at cols 43-47: col 43=B, 44-46=p, 47=B) → stops at rows 18-22 → per the death model → death.
- If the collision is the 3-wide core (cols 44-46): also blocked at rows 13-17 by the purple.
Both die. Bad experiment.
Better experiment to determine the collision width safely: is there a place where the sprite can rise a bit and stop WITHOUT a purple above? Hmm, in this maze, no (all rises lead under a purple).
Alternative: test the collision width using the WALL rows. E.g., the sprite at L=37 in its room: if I destroy the brick at rows 31-35 cols 37-41, the sprite rises; the halo (cols 37-41) fits exactly in the 5-wide hole. If the halo needed 5-wide clearance and the hole is exactly 5 wide, fine. Not discriminating.
Let me think about whether the "blocked rise = death" model is really right, bec

**Pensamiento:**

Wait! Look at L=37: 'wall', 37..41 → the sprite's own halo cells are counted as wall (of course, they're the sprite's black halo). Also note rows 0-12 at cols 37-41 are wall, and rows 13-17 have hazard + wall.
Hmm, hold on! Something important: at L=37, rows 37-41 show 'wall' — but that's where the sprite IS. And rows 31-35 = brick ✓.
Now, the crucial finding: NO column L has a clear path to row 0 even after removing all bricks:
- L=31: rows 0, 6, 12 are wall (indestructible), rows 30-36 wall/brick. Hmm, rows 1-5 and 7-11 are bricks ✓ clearable, but rows 0, 6, 12 are wall. However! Destroying a brick opens the wall row above/below it: destroying the brick at rows 1-5 cols 31-35 opens rows 0 and 6 at cols 31-35; destroying the brick at rows 7-11 opens rows 6 and 12 ✓. So at L=31, rows 0-12 can ALL be cleared (by destroying the 2 bricks) ✓✓.
- L=31, rows 31-36: rows 31-35 are mostly WALL (only a few brick cells: (31,32),(34,31),(35,34) — those are the G/N border cells of the bricks at cols 37-41? no...). Hmm, at L=31 rows 31-35, the cells are mostly 'B' (wall) with a few stray N/G from the adjacent bricks' borders. So cols 31-35 rows 31-35 = solid wall → the sprite can NEVER rise at cols 31-35 through the band. Confirmed.
So the sprite can never rise at cols 31-35 from below. But it could rise at cols 31-35 from WITHIN the big room (rows 13-29) — if it could get into the big room, it could move left to L=31 and rise to row 0 (after destroying the 2 top bricks) ✓✓✓.

**Pensamiento:**

The top shaft is now open: cols 31-35, rows 0-13 all sky ✓. The escape route exists (from within the big room at L=31).
Now the risky step: click (33,39) to open the band at cols 37-41 → the sprite rises into the big room and stops at rows 18-22.
Before that, let me consider one alternative that avoids the intermediate stop entirely: what if I could make the sprite rise at cols 31-35 directly from its current room? Blocked by the wall at rows 31-35 cols 31-35 (solid black, indestructible). Confirmed.
Alternatively: is there any way the sprite could get into the big room without a rise? No, the sprite only moves horizontally and rises.
So: the intermediate stop is unavoidable. Let me do it as a single action and check the outcome immediately (if I die, the level resets and I try a different idea).
Hmm, wait. Before the risky click, let me reconsider ONE more time whether the wave-1 death could be explained by something I can avoid. 
In wave 1, the sprite rose into the small room (rows 13-23, cols 13-29) and stopped at rows 13-17. Note: the small room's ceiling (row 12) was SOLID at cols 13-17 but had gaps at cols 18 and 24 (1-wide, rows 7-12). So the room was "connected" upward via 1-wide gaps to the purple region. Hmm.
Alternative explanation for the wave-1 death: the sprite rose into the small room and its halo was squeezed because the room was 17 wide... no.
Another thought: maybe the sprite dies when it rises into a room whose ceiling is a "wall with the purple objects abo

**Pensamiento:**

DEATH AGAIN — with the top shaft open! The bar was ~9 (not depleted). So the death is NOT about the escape route being open.
So: **the sprite dies when its rise is blocked mid-maze** (regardless of other escape routes). That's now confirmed twice:
- Wave 1: rose at cols 13-17 into the small room, blocked → death.
- Wave 2: rose at cols 37-41 into the big room, blocked → death (even though a shaft to the top existed elsewhere).
And the sprite survives when its rise reaches row 0 (the top of the board) — steps 35, 37, 55.
So the rule: **ANY rise must go all the way to the top of the board. If a rise is blocked before reaching row 0 → death.**
Therefore: never trigger a rise unless the sprite's current column has a clear path to row 0 (after clearing bricks).
Now, in the current (reset) maze = wave 1 again (the level restarts from its initial state). Wave 1's maze:
- Sprite at L=19 (cols 19-23) rows 37-41 in the bottom room (rows 37-62, cols 13-53).
- The band rows 24-36: bricks at rows 25-29 and 31-35, cols 13-17, 19-23, ..., 49-53 (7 columns × 2 rows = 14 bricks).
- Above the band: rows 13-23 = the small room (cols 13-29) and rows 0-23 = the top-right room (cols 37-53).
- The purple objects at rows 7-11 cols 14-16, 20-22, 26-28 (above the small room).
- Row 12: wall with 1-wide gaps at cols 18, 24 (rows 7-12)?
So in wave 1, the escape columns are those in the top-right room: cols 37-53 (open rows 0-23) ✓. So the sprite must rise at cols 37-41, 43-47, or 49-53: destroy the 2 br

**Pensamiento:**

The sprite rose from rows 37-40 to rows 19-22 (frame 15) and then at frame 16 it was crushed (2 cells) and vanished. So it stopped at rows 19-22 (the halo top at row 19, blocked by the wall at row 18) — right below the purple object (rows 13-17) — and died.
So in wave 2, the sprite CANNOT survive entering the big room. And no other rise is possible. So wave 2 (as I understood it) must not be the intended state... 
Hmm! Unless the wave-2 maze is different when entered properly. Note: I entered wave 2 via the escape at cols 37-41 (the sprite exited at row 0 near cols 37-41, then dropped into the new maze and landed at the notch at cols 37-41 rows 37-41).
What if the new maze's layout depends on where the sprite exits?! Or what if the sprite's landing position in the new maze is determined by the exit column, and the maze itself is fixed? The maze is fixed (deterministic), but the sprite's landing position may vary with the exit column!
If the sprite exits at a different column, it would land at a different place in wave 2 — e.g., in a different room, from which an escape exists!
That's a promising hypothesis: the sprite's entry position in the next wave = the exit column. In wave 1, I could exit at cols 37-41, 43-47, or 49-53 (any column in the top-right room) — or even at cols 13-29 if the small room reached the top (it doesn't).
So: exit wave 1 at cols 49-53 (the rightmost) → the sprite might land in a different room in wave 2 (e.g., the right side lower down, or a different

Excellent! This crop (frame 3 of the fatal animation, i.e., right after the click destroyed the brick at rows 31-35 cols 37-41) reveals the true structure of wave 2 in that region:
Row 30: cols 38-42 = S (the opened wall row!) — wait: row 30 = "BBBBBBBBBSSSSSBBBBBBBB" for cols 28-49 → cols 28-36='B', 37-41='SSSSS'... let me index: index 0 = col 28. So 'B' at 28..36 (9 chars), then 'SSSSS' at cols 37-41 ✓, then 'B' at 42-49.
Row 36: "BBBBBBBBBSSSSS..." hmm row 36 = "BBBBBBBBBSBBBSBBBBBBBB" → cols 37='B'? index: 0-8 = B (28-36), index 9 = 'S' → col 37 = S, then 'BBB' (38-40), 'S' (41), then B... 
So row 36 (the wall row below the destroyed brick) opened only at cols 37 and 41 (the sides), NOT at cols 38-40! Because the sprite's halo occupies... no wait, this is frame 3, before the rise. Hmm, interesting: row 36 shows S at cols 37 and 41 but B at 38-40.
Hmm! And rows 37-41 at cols 37-41 show the sprite's halo ('BBbBB', 'BbbYB', ...) — the halo occupies cols 37-41 rows 37-41 ✓.
So row 36's cells at cols 38-40 are 'B' — hmm, why? The brick destruction opened row 36 at cols 37 and 41 only? That's weird. Unless the wall row below a brick opens only partially... 
Hmm, look at wave 1's first death: when I destroyed the brick at rows 31-35 cols 13-17, the timeline step 1 said: 'B>S @ (30,13)...(30,17), (36,13),(36,17)' — the same pattern! Row 30 opened fully (5 cells) but row 36 opened only at the two side columns (13 and 17), leaving cols 14-16 as wall.

The hole at cols 49-53 is now fully open from row 24 to row 36 (rows 24-36 all 'S' at cols 49-53) ✓, connecting the top-right room (rows 0-23) to the bottom room (rows 37+).
Wait, look at the crop: rows 24-36 at cols 49-53 = 'SSSSS' ✓ (and the wall rows 24, 30, 36 all opened). 
Hmm, interesting: the crop shows cols 47,48 = 'N','B' etc. — the brick at cols 43-47 remains (col 47 shows N/G = its right border). And cols 54-55 = 'B'.
So: destroying both bricks at a column opens rows 24-36 completely ✓.
Now, the sprite is at cols 20-21 (blue) → L=19. To escape at cols 49-53, I press RIGHT ×5 → at the 5th press the sprite is at L=49 → rises → up through the hole → to row 0 → escape ✓.

**Pensamiento:**

The wave advanced again (the sprite escaped at cols 49-53) and the new maze (wave 2 again?) looks VERY similar to the previous wave 2: the big room rows 13-29 with 3 purple objects at rows 13-17 (cols 38-40, 44-46, 50-52), the top shaft bricks at rows 1-5 and 7-11 cols 31-35, the band rows 31-47 with bricks at cols 13-35 (rows 37-41 and 43-47) and rows 31-35 at cols 13-17, 37-41, 43-47, 49-53.
BUT the sprite landed at cols 50-51 (blue) → L=49, in the RIGHTMOST column of the right room, and the right room is now at cols 43-53? Let me look at the image: the right room (sky) spans cols ~43-53 rows ~43-62, and the sprite is at the top-right (rows 37-41 cols 49-53). Hmm, and there's a brick at rows 37-41 cols 43-47 (visible in the image as a green block at the sprite's left).
So the landing position DID depend on the exit column ✓ (last time I exited at cols 37-41 and landed at cols 37-41; now I exited at cols 49-53 and landed at cols 49-53).
And the maze is the SAME wave-2 maze as before (deterministic), but the sprite is in a different position within the right room!
Now: the sprite at L=49 (cols 49-53). The band above: rows 31-35 has a brick at cols 49-53 → destroy it → the sprite rises into the big room → blocked by the wall at row 18 (cols 49-53) → death. Same problem.
Hmm. So the wave-2 maze is the same and unsolvable...

**Pensamiento:**

Level-1 data:
- Step 19: N=0 (all bricks cleared), sprite at rows 37-40 cols 32-33 (L=31).
- Step 20 (RIGHT): the sprite moved to cols 38-39 (L=37) and S decreased 2056→1823 (the maze partially changed: 357 cells).
- Step 21 (RIGHT): the sprite moved to cols 44-45 (L=43) and N=189 (a NEW maze appeared — the wave advanced!).
So the wave advanced at step 21, and the sprite was in the bottom room (rows 37-40) — it did NOT escape upward. So a wave advance CAN happen without an escape.
What triggered it? The most likely: all bricks cleared (at step 19) → the wave advances a couple of actions later. Or: the maze advances after a fixed number of actions? Hmm, at step 20 the maze partially changed (357 cells) — that's odd for a "no-op" RIGHT.
Hmm! Maybe the wave advance is animated over ~2 frames/steps: at step 20 the animation's first frame was captured (357 cells changed) and at step 21 the final state. But no — each step is a separate action with its own final frame.
Hmm, unless the wave advance animation spans multiple frames and the frame captured at step 20 was mid-animation (the animation continued into step 21's action). Possible: an action's animation may not have finished before the next action.
So the wave advance likely happened at step 20 (triggered by the RIGHT at step 20), and the frame at step 20 was mid-animation, step 21's frame = the settled new maze.
So: the wave advance was triggered by the RIGHT at step 20, which was 1 action after clearing the last brick.
Hmm,

**Pensamiento:**

At step 19 (level 1 wave 1), the column at cols 36-42 was open from row 0 to row 29 (all sky!) and rows 30-36 were wall (with G texture dots), then rows 37-40 sky (the room).
So at step 19, the brick at rows 31-35 cols 37-41 was... hmm, rows 31-35 at cols 36-42 show 'B' with a few G dots — so NO brick there at step 19?! But N=0 at step 19 (all bricks cleared) ✓ consistent — the bricks' cells became 'B'?? 
WAIT. That's important! When a brick is destroyed, do its cells become SKY or BLACK? At step 19 (after clearing all bricks), rows 25-29 at cols 36-42 = 'S' (sky) ✓ but rows 31-35 = 'B' (black/wall)!
Hmm, so the bricks in the LOWER band row (rows 31-35), when destroyed, leave BLACK cells, while the upper band row (rows 25-29) leaves SKY?
Hmm, that doesn't match my level-2 observation where destroying the bricks at rows 25-29 and 31-35 cols 49-53 gave sky at rows 24-36 ✓ (all S).
Hmm, unless at step 19 in level 1, the lower band rows 31-35 were NEVER bricks in that region. Let me reconsider the level-1 wave-1 maze: maybe the band was at rows 25-29 only (one row of bricks) and rows 30-36 was just a thick wall. Then at step 19 (all bricks cleared), rows 25-29 = sky ✓ and rows 30-36 = wall ✓. That's consistent!
So in level 1 wave 1, after clearing all bricks, the column at cols 37-41 was open from row 0 to row 29, but rows 30-36 were SOLID WALL (7 rows) → the sprite at L=37 could NOT rise. ✓ So no rise at step 20 → the wave advance at step 20 was NOT caused by an escape.
