Credit goes for fnuga12 for the costumes, and nearly full credit goes to mcyoda and Brotascos for the simulation. Also thanks to SomeRandomStickBoy for the jump script! Next update: working inventory so you can't have a dirt block in your hand if you don't have one, and more music and texture packs!
