XBOX-style PC gamepad support added to Meteor Slime!

Hi! Neils4 here with some great news! I was able to add XBOX-style PC gamepad support to Meteor Slime! I also added two new characters: a boy wearing goggles and a UFO! The game controls much better now! I hope to improve the game and try to submit it to the Steam online gaming service. Give it a try! ^_^
