Very nice! The graphics are very well done and the music is so adequate! The increasing difficulty was nicely developed. I found a bug, where going through the same ring multiple time was being counted as separate rings. It happened to me quite a few times, but tried to find the solution that goes though all the rings! The last level was very tough! Really nice game, in such a short time. I coudln't stop until I beat all the levels! An yeah, cool name!
