Done! I've created a complete Dangerous Dave-style tile-based platformer in a single HTML file. The game features: **Gameplay:** - Navigate through procedurally generated levels to grab the golden trophy - After collecting the trophy, find the exit (green door) to complete the level - Avoid hazards: fire, water, spikes, and lava - Defeat or avoid enemies (red patrol enemies and green jumping enemies) - 3 lives with score tracking **Controls:** - Arrow keys to move left/right - Spacebar to jump - Procedural pixel-art graphics (no external assets) - Smooth camera following - Animated character and hazards - Multiple enemy types with different behaviors - Increasing difficulty with each level Simply open `index.html` in a browser to play! The game generates a new random level each time you restart.
