Fidget Ball Tap app for iPhone and iPad

If you are tired of high-pressure games in this high-pressure world and you take a break, this is the game for you.
We wanted to make this game (our first) to be super simple. We wanted it to be the kind of casual game you can take out anytime and just get your mind off of everything.
There are 3 different levels (so far). 1) gives you 3 blue balls tap one pop, its gone and another takes its place. 2) When you tap a ball 2 blue balls take its place for an even more satisfying visual effect. 3) The balls multiply, but this time they change color, making for a rainbow ball effect.
For a challenge, you can add a timer.
