Slime invaders

Oh no! Horrid green and purple monsters have landed from outer space! Can you and a friend shoot them an arbitrary amount. The game is intended for two local players but can be enjoyed by one player.

Originally this started as a space tutorial game from GameMaker but I have made it my own by adjusting the enemies, adding my own art, adding a new player, adding sound, adding rules and other general edits.
