Your goal in Shape Shifter is to gather stars, try to get to the exit and clear each level. You can do these things by switching from one form to another!
A mouse, a rabbit, and an elephant were all just hanging out in their best clothes when a witch showed up and cursed them all into one body. In each level, you need to use either [WASD] or the [ARROW] keys to move and jump, and the [1], [2], and [3] keys to swap between characters, each of which has their own abilities. The elephant can smash through big obstacles, for instance, while the mouse can fit through tiny paths and can eat cheese.
