Wow! thats really good :)
The idea is fantastic and the execution as well, it has a "serious" atmosphere inside each room with the darkness and saw sounds, but the funny music kicks in and you see this funny look fella, it works very well.
Gameplay wise its also very entertaining, the only thing i would change is the fact that there's some kind of a delay between each clicks (i used the mouse), u can't really change direction and jump right away, its not very snappy or responsive.
great submission!
