Polka Sheep

Polka Sheep is a goofy platformer where you only use one button (I believe it was made as part of a game jam with a theme of using 1 button) to jump and since you're a sheep you can stick to walls and platforms like velcro in order to climb higher and free your fellow sheep. A creative concept and game mechanic that I thought was pretty fun.
