I see you've shared a simple 2D Minecraft-style game. What would you like me to do with it? Some options:

1. **Fix/improve it** - Add gravity, collision detection, better controls
2. **Add features** - Inventory, multiple block types, day/night cycle
3. **Convert to Playscape SDK** - Make it mobile-compatible with touch controls
4. **Enhance visuals** - Generate proper sprite assets instead of colored rectangles

Let me know what you'd like!
