Could be a good game. Ads are pretty much mandatory in any game now but there are alot here. The main issue I have is the game physics are wrong. I've played a few games like this one that worked better. Quite often the lines the balls are taking are changed after hitting the top. The balls change the direction they are travelling and head towards the bottom sharply instead of taking the natural planned route. This is a programming tactic designed to make you fail and spend $.
