Up/Down - Move up/down Space - Shoot Shoot the Aliens and don't let them get into the atmosphere. When they do, they will breathe Earth's air and the foreign chemicals will mutate them so that they are strong enough to move Earth into their own solar system and claim us as slaves. Your job as Earth's chosen astronaut is to ward 30 of them off with your spaceship's ray gun.
The general idea is originally by me. I drew the sprites, encoded the scripts, and made the backstory all myself. Music by Rakohus, Laser SFX by SFX Planet.
