Literally just Galaga but bad. Left Arrow to move left, Right Arrow to move right, Space to shoot. If enemies touch you you're ded. (Warning: The game over music is very loud.)
I made this absolute train wreck of a game for a school assignment and I actually kinda liked doing it. All coding is by me, and all the sprites are terribly drawn ripoffs of Galaga sprites, so thanks to the makers of Galaga I guess.
