The user wants me to build a tile-based platformer game in the style of Dangerous Dave. Let me plan out what I need to include:

1. **Canvas-based rendering** - All graphics drawn procedurally
2. **Tile-based level system** - Grid-based level with different tile types
3. **Player character** - Can walk and jump
4. **Goal** - Grab a trophy, then reach exit
5. **Hazards** - Fire and water that kill the player
6. **Enemies** - Simple patrol enemies
7. **Platforms** - Solid ground to walk on
8. **Physics** - Gravity, jumping, collision detection

Let me create a complete, self-contained HTML file with:
- CSS for styling
- Canvas for the game
- JavaScript for all game logic
- Procedural graphics (no external images)

I'll design a level layout, implement player controls, add hazards, enemies, and the trophy/exit mechanics.
