Apsis

Apsis is a simple and addictive physics game where you control an orbiting rocket ship in deep space. The object of the game is to collect all the stars in each level as fast as possible and without running out of fuel. Watch out for planets, because each one has gravity that pulls your ship towards it and can eventually collide with it. Orbit these planets and perform burns just like NASA does to conserve fuel and slingshot your way to victory. Once you complete the 24 action-packed levels, you can unlock the Editor and make levels of your own.
