Mutant Storm

The inhabitants of a world, far away, are been hit by dark ray and have been transformed into rampaging mutants. Your job is to kill those mutants. You are controlling a tiny space craft, which is centered on the screen when you start a level. However, you can move your craft with your keyboard to any point on the screen. You are aiming your weapon with your mouse. Your job is now to kill anything on the screen, while avoiding all enemies. If they touch you, your ship explodes and you have lost a life. Once the last enemy is gone, you proceed with the next level. There are 89 different levels to play.
