This game from IFComp 2005 was a pleasant surprise. You play as a retired clown trying to find his kids on a circus island.
It's simple and innocent fun, with varied locations and an honestly unique setting. The only other circus game I know well is Ballyhoo, and this is quite different from Ballyhoo.
However, it suffers a bit from 'walkthrough-itis'. It's pretty clear that the author had some awesome actions scenes and clever puzzles in mind, but the game doesn't really clue you into the required actions all that well.
I still enjoyed this game quite a bit.
