Done! Now when green blocks break, there's a 15% chance they drop a yellow star power-up. When caught by the paddle, it spawns 4 additional balls from the first active ball's position (making 5 total), each flying in random upward directions.

**Next Ideas:**
1. **Multi-ball indicator** - Show a ball counter in the corner so players know how many balls are active
2. **More power-up types** - Add paddle width increase, slow-mo ball, or laser shots
