You are the blue spaceship. Try to shoot the aliens. Dodge the missiles. The yellow and light blue ones immobilize your ship for a couple seconds. The red one ends the game. You only have a certain amount of ammo. Your ammo regenerates though. You also need to hit the green flag twice.
All of the code here is by me. This project has been redone for Scratch 2.0, in that it now uses cloning rather than 30 sprites.
