Ball Buster is a survival game for the iphone and ipod touch. The idea of the game is to keep your blue ball alive for as long as possible without touching the red balls that keep coming. Each new level throws another red ball into the mix, making the game just that much harder. The player moves the blue ball with their finger. Which can get a bit cumbersome after a while due to the amount of screen blocked by your finger. With each addition of a red ball, you will notice your finger more and more because there are always about 2 balls hidden behind it that could be coming to tag you.
