I'm sorry to say, but the game is not fun at the moment. You completely lack the ability to control anything besides a very temporary gain in stats.
It's completely luck based when balls collide with eachother. It took me upwards of 10 minutes waiting to get past wave 1. You definetly need some sort of control over your balls.
Also, it would be nice if you could color/mark the players' balls differntly so as to know which ability you have to press.
BUT I appreciate your effort and hope you continue to learn and to build more games!
