Done! I've transformed the game into a Beyblade battle game with:

**Gameplay:**
- **Turn-based launching** - Player 1 launches first, then Player 2
- **Swipe/drag to launch** - Works on both mobile (touch) and desktop (mouse)
- **Launch power** - Longer swipes = more power and spin
- **Physics-based combat** - Beyblades collide, bounce off walls, and lose spin over time
- **Sloped arena** - Beyblades naturally drift toward the center

**Win conditions:**
- Opponent's spin drops to zero
- Opponent gets knocked out of the arena

**Features:**
- Custom player names and colors
- Spinning Beyblade visuals with 3-blade design
- Trail effects and collision sparks
- Real-time spin meters
- Golden arena with decorative rings

**Next Ideas:**
1. **Special Attacks** - Add a boost button that temporarily increases spin or creates a powerful collision wave
2. **Multiple Arenas** - Different shaped arenas (hexagon, square) with unique obstacles and hazards
