Fun little game!

The graphics are pretty tight, the physics and Gravity is on the money, and the asteroid target practice is awesome. Its excellent when the suns Gravity is maxed out, curving the trajectory of your roids for more challenging targeting. With such a great foundation, there is a lot of room for expansion in future updates (perhaps binary systems with each star playing for Gravity, user customizable planet scapes, close up world mode where you enter a sub game and build planets from core to mantle, to the and terrain). I definitely recommend this game...its a load of fun!!!
