Your rocket has been hit by an Uncontrollable virus, so you cannot turn left or right. The rocket is currently aiming at an unknown planet, you have no idea at all where it is going. Fly through hordes of enemies, including Boomy Puffs that can explode, space ghosts, and poisonous space bugs. Use the up arrow or W to move up, and the down arrow or S key to move down. EDIT: I have improved it slightly, with text to speech and a few bugs fixed.
Credit to Coding for Beginners Using Scratch book from Usborne. I took the idea from the Space Adventure game. There's a sequel coming, once it's released I'll comment on to my profile the name. (You can also access it on my profile, you don't have to search it!)
