It's a simple tilt & maneuver game where you control a spaceship through an asteroid field and dodge asteroids while going at warp speeds.
the game has the basic three difficulty level easy, medium and hard and these levels are differentiated by the speed your space craft is traveling. you points are gained by how long you can survive on the field... GOOD LUCK
It doesn't get any simpler than this, just requires your average focus, it's pretty much your leisure game, something you play while sitting at home waiting for the pizza guy to deliver the pizza.
