I like the game so far. Although the boss battles do tend to drag on for quite a while. Some of the tickling scenes are also a little long, but that's fine. Also, like others have said, the backtracking and washing can be repetitive and tedious.
All in all, this is a good, creative game. I hope you'll make more games like this in the future.
By the way, I see this small brush in some of the tickling scenes. Is that supposed to be there?
