Pretty glitchy. I love this game to death but the transition to flash... It just doesn't work. The controls lag too much and sometimes I get stuck spinning in one direction. 3 stars.
Playing the game perfectly as far as I can tell. My game goes game over on me for no reason. This is the 6th time its happened. 1/5. The only thing I can think of is that you can run out of rings to use per level... That would explain it. But I've looked at the instructions 3 times and saw nothing about that.

 "Rings"){kind=icon}
