Random Update

I've been playing Box Blast from time to time on my own, and there were too many glaring issues that I wanted to fix, which I couldn't ignore, even in a game that was over a year old by now!

Here are the changes:

1. Made the UI buttons less ugly-looking
2. Made the music shuffle, instead of loop
3. Added a new possible music track
4. Throwing a grenade no longer slows you down as much
5. If the combo is above 5x enemies killed, you gain that amount of health(e.g., if you kill 10 enemies in a row, you gain 10 health)
6. Fixed being able to hit dead enemies with bullets
7. Made the color palette more variable
