The user wants a complete, self-contained HTML file with a tile-based platformer game inspired by Danger Dave. Let me plan out the features: 1. **Tile-based platformer** - Grid-based levels with different tile types 2. **Navigate a level** - Player moves left/right and jumps 3. **Grab a trophy** - Collectible item 4. **Reach the exit** - Door/exit tile 5. **Avoid hazards** - Fire and water tiles 6. **Jumping** - Physics-based jumping with gravity 7. **Simple enemies** - Enemies that patrol back and forth 8. **Procedural graphics** - All drawn on canvas, no external assets 9. **No external resources** - Everything inline Let me design this: - Tile sizes: 32x32 pixels - Level format: 2D array of tile characters - Player: small sprite drawn with canvas primitives - Platforms: solid blocks - Fire: animated orange/red tiles - Water: blue animated tiles - Enemies: simple walking sprites - Trophy: golden collectible - Exit: door tile I'll create a complete game with: - Multiple levels (procedurally generated or hand-crafted) - Score tracking - Lives system - Smooth movement with collision detection - Animated graphics Let me build this out fully.

MEASUREMENTS
Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
