Centripetus app for iPhone and iPad

Shoot the spheres that are surrounding you, but please, dont hit yourself.
But after all, why should I destroy these spheres? Why the shots always come back to hurt me? What are our real goals? Why should I play this game? I have no idea.
- Shoot the spheres. Do not ask why. Just destroy them.
- If you shoot yourself, its over.
- 3 sets with 20 levels each, with more levels on the way.
- Discover different patterns of circular and elliptical movements. (Wow, how exciting)
- Discover the spheres power-ups.
- Find out that you do not have any power-up.
- Stay upset. But remember that if you have reflexes and perseverance, you will always have another chance.
