The user wants me to create a tile-based platformer game in the style of Dangerous Dave - a classic 80s/90s platformer where you navigate a level, collect a trophy, and reach the exit while avoiding hazards.

Let me create a self-contained HTML file with:
1. Canvas-based rendering
2. Tile-based level design
3. Player character with jumping mechanics
4. Collectible trophy
5. Exit door
6. Hazards (fire, water)
7. Simple enemies
8. All procedural graphics (drawn with canvas API)
9. No external resources

I'll structure the code with:
- CSS for basic styling
- JavaScript with game state, rendering, physics, collision detection
- Tile map system
- Entity system for player, enemies, hazards, collectibles
- Keyboard controls

Let me write this comprehensive game in a single file.
