Mr. Bunny was captured and given experimental gravity controlling powers by an evil corporation! Try to escape from the confines of the mad science laboratory and discover the truth! Controls are visually covered in the beginning of the game, which includes moving with the arrow keys, and jumping with space. When encountering gravity, you can also reset gravity to normal with S. Have fun!
