My favorite so far. Really like the music and effects. Some issues though:

- It can be hard to see balls as they are rather dark. Maybe just a little brighter OR you could make the player ball glow brighter so that you can see nearby balls better.

- You can hit the same ball more than once after it has been lit.

- Some balls would light up multiple balls even though I didn't touch the other ones.

- Movement can be a little difficult, especially when moving vertically.

- There is no score provided at the end.
