Nice little game! A few issues, though:
- If I collide with the edge of the mouse's butt as it's walking away, I still die. The collision detection for this should be at the mouse's head, preferably only 1-way.
- Transforming to/from a raisin makes me move forward very slightly, so I can end up falling into gaps unintentionally.
- The music doesn't loop once it ends.
