A strage wormhole has appeared in space, andit pusles with a musical beat, spitting out dangerous asteroids. Using the newly designed piece of equipment, M.U.S.I.C. (Multi-Universal stabilization and inspection contraption), protect the planets from the incoming asteroids. The planets will attract the asteroids because of gravity. M.U.S.I.C., controlled by the mouse, will repel the asteroids. The game ends when 25 asteroids hit the planets.
