A bit unclear to begin with without knowing the controls beforehand. Perhaps make it so that if you hold the grab button the ball starts rolling your way (as if you're grabbing the chain)? It's a bit tricky to move accurately with the physics and I'm not really sure what that patrol camera-like thing was supposed to do, pull you in? I also got stuck in a corner twice and had to restart.
An interesting concept though, just some more tweaks and it could be really interesting!
