Great entry. At first I thought I wouldn't enjoy playing it but as I played more and more I got a bit hooked. Teleport mechanic is way cool.
The controls do feel a bit over-responsive which makes it hard to navigate out of tight spots. Some inertia on the ball would feel good. I also wanted to be able to speed up and slow down.
With a bit more polish and a couple of features added this could be a seriously addictive game.
