- **HP**: 100 (max)
- **Cursed Energy (CE)**: Varies by character (0-100 max) 
- **Signature Ability**: Each character has their iconic move

The player object loads this data into `player.userData` when the battle starts.

**Next Ideas:**
1. **HP/CE HUD Overlay** - Display health and cursed energy bars on screen with character name
2. **Signature Ability System** - Press ACTION key to trigger each character's ultimate move with CE cost
