Not a fan.
As stated in the last review, it's too much guess then let the ball bounce aroudn for several minutes before it finally manages to hit the goal. Unless you're like me and manage to get the ball on top of one of the walls.... It's obvious that you didn't use an entire object for the collision detection, just the boundary. No worries, though. It was rather boring, in my opinion; there juset wasn't much to do.
