Built a 3D fighting game using your world GLB as the arena. Features:
- **2 player local versus** - P1 uses WASD + F/G for attacks, P2 uses Arrows + J/K
- **Collision with your world** - Uses Octree for proper collision detection
- **Combat system** - Punch, kick, blocking (hold back), knockback
- **Best of 3 rounds** - Health bars, round tracking, win conditions
- **Epic battle music** and sound effects

**Next Ideas:**
1. **Special Moves** - Add combo inputs (down+forward+punch) for fireballs or uppercuts with unique animations
2. **AI Opponent** - Single player mode with a computer-controlled fighter using basic combat AI
