This is an "Alien Blaster" platformer game with:
- Player that moves, jumps, and shoots bullets
- Aliens that patrol and can be shot or stomped
- Spikes that kill on contact
- Score system with coins rewards

The game is fully functional. What would you like me to do with it?

**Next Ideas:**
1. **Power-ups** - Add temporary shields, rapid fire, or double jump collectibles
2. **Multiple Levels** - Create progression with new alien types and platform layouts
