Done! I built a **2D fighting game** with:

- **Two fighters** - Player 1 (blue) vs Player 2 (red)
- **Controls:**
  - P1: WASD to move, J=punch, K=kick, L=block
  - P2: Arrow keys to move, 1=punch, 2=kick, 3=block
- **Combat system** - Punches (fast, less damage), kicks (slower, more damage), blocking (reduces damage)
- **Health bars** and **round system** (best of 3)
- **Sound effects** for hits and blocks
- **Pixel art** dojo arena background and fighter sprites

**Next Ideas:**
1. **Special Moves** - Add combo attacks or a super meter that builds up for devastating finishers
2. **Character Selection** - Add 2-3 more fighters with unique stats (fast/weak, slow/strong)
