This is not completely done, but the actual game part of it is. Use <-/-> to move left/right Press and RELEASE space to shoot I'm not sure why, but whenever you lose a life, the next time you press and release space it doesn't shoot. 1 or 2 aliens fly down at you at a time except for when a yellow alien flies down as yellow aliens take two red aliens with them. Each alien can fire 3 or 4 times with random delay. If an alien goes past the bottom of the screen, it goes back in formation. This is based off the game "Galaxian". I tried to make it as realistic as possible, but a) it's Scratch b) I'm not the best at coding
Credit to Namco for the original game This is NOT Galaga! Galaxian is the original in the Galaga series. Galaga is the sequel to Galaxian.
