This is a really well executed idea leading to some pretty fun gameplay. Although it could easily be made more engaging by adding a few more sound effects (e.g. the head bouncing on the walls/floors, a sound effect for every 10 points)
Thanks a lot! There are already sound effects for the wall and floor bounce but perhaps they are a bit low in the mix if you have the volume turned down. A sound effect for every 10 points is a really nice idea.
