Build a playable tile-based platformer on a canvas in the Dangerous Dave style: navigate a level to grab a trophy and then reach the exit, avoiding hazards like fire and water, with jumping and simple enemies. Procedural graphics only, no external assets.

The user wants me to build a tile-based platformer game in the Dangerous Dave style. This means:

1. A canvas-based game
2. Tile map navigation
3. Platforms to walk on
4. Hazards to avoid (fire, water)
5. A trophy to collect
6. An exit to reach
7. Simple enemies (moving platforms or squishable enemies)
8. Jumping mechanics
9. Procedural graphics (no external assets)
10. Single file with HTML, CSS, and JS

Let me create a complete game with:
- A tile-based map system
- Player character with physics (gravity, collision, jumping)
- Multiple hazard zones (lava/water)
- A trophy at the goal
- Simple enemies (spike blocks or moving platforms)
- Victory condition

I'll make this self-contained and playable in a browser.

The file was cut off. I need to complete it by writing the full game. Let me rewrite it properly.

Let me write the complete game:

write /tmp/ws/game2.html (28705 bytes)
toolResult

Successfully wrote 28705 bytes to /tmp/ws/game2.html

assistant
thinking
That file has too much garbage in it. Let me write a clean, complete game from scratch with proper structure.

Let me write a clean, working implementation:

bash {"command":"rm /tmp/ws/game2.html /tmp/ws/index.html 2>/dev/null; cat > /tmp/ws/index.html << 'GAMEEOF'\n<!DOCTYPE html>\n<html>\n<head>\n
toolResult

(no output)

assistant
thinking
The file was truncated badly by the heredoc. Let me write a clean, complete game to a new file step by step.

Let me write a working game with a proper approach - creating a new file with all content:

bash {"command":"cat > /tmp/ws/index.html << 'ENDOFFILE'\n<!DOCTYPE html>\n<html>\n<head>\n<meta charset=\"UTF-8\">\n<title>Dangerous Platformer<
toolResult

/bin/bash: line 508: warning: here-document at line 1 delimited by end-of-file (wanted `ENDOFFILE')

assistant
thinking
The file was too large for a single heredoc. I need to build it incrementally or use a different approach. Let me write it in chunks.

Let me create the file properly by writing it directly:

bash {"command":"cd /tmp/ws && python3 << 'PYEOF'\nhtml_code = '''<!DOCTYPE html>\n<html>\n<head>\n<meta charset=\"UTF-8\">\n<title>Dangerous Pla
toolResult

/bin/bash: line 1: python3: command not found Command exited with code 127

assistant
thinking
No python3 either. Let me try just creating a proper simple game file using bash echo with manual line breaks.
bash {"command":"cd /tmp/ws\n\ncat > index.html << 'EOF'\n<!DOCTYPE html>\n<html>\n<head>\n<meta charset=\"UTF-8\">\n<title>Dangerous Platformer<
toolResult

File created

assistant
thinking
Good, the file was created. But it's a very basic template. Let me write a more complete and playable platformer game in a separate write approach.

Now let me write a fully functional game with proper mechanics:

write /tmp/ws/index.html (3355 bytes)
toolResult

Successfully wrote 3355 bytes to /tmp/ws/index.html

TAKE IT TO CODE

A single self-contained HTML file — copy it and open in any browser, or reuse the prompt with your own pi-agent run.

EVALUATION

1/5 broken

Only a blank canvas with HP/Score HUD text is rendered; JS syntax error prevents the game from drawing.
