This is a great idea, and I really liked the sound design and the character design. I kinda wish the torso tumbled around on the floor, and then changes to pull itself along or walk depending on limbs attached, but that's work.
I have one question: How does it read the notes without a head?
Some feedback: I think the camera movement direction should be inverted. I would have really liked an in-game menu, cause I accidentally hit escape to put down a letter and it kicked me back to the start menu and lost all my progress.
That aside, great job on your game!
