The user wants me to create a tile-based platformer game in the style of Dangerous Dave. This should be a single self-contained HTML file with: 1. Canvas-based rendering 2. Procedural graphics (no external assets) 3. Tile-based level design 4. Player movement with jumping 5. Enemies that move around 6. Hazards like fire and water 7. Objective: grab a trophy and reach the exit 8. All CSS in `<style>` tags 9. All JavaScript in `<script>` tags 10. No network requests or external resources Let me create a complete, playable platformer game with: - Pixel art style graphics rendered procedurally on canvas - A level system with tiles (ground, walls, platforms) - Player with gravity, jumping, collision detection - Simple AI enemies (patrolling) - Hazards (lava/water that kills player) - Trophy to collect - Exit door that only opens after collecting trophy - Smooth animations and effects I'll write this as a single index.html file.

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.
