Really nice game, graphics and gameplay, although I don't get the secret part. Also, it would be better if the player had a bit more mouse sensitivity, or have it customizable.

The idea is fantastic. I think this could be a real commercial product. The controls and animations are satisfying. Being able to change skin is a nice feature. The jumping puzzles are a nice touch, and can make for some fun interactivity if multiplayer. I would definitely create a room and have friends join. Good job
