Like many of Donut Games' games, the controls are very easy to use and understand, with a button for acceleration and two buttons to steer left and right. You need only steer your spaceship around the asteroids, avoiding the walls and occasional missle whilst trying to hit the boosters for some extra speed. There are also some shield powerups to help keep your spaceship alive as you rocket through the levels."
