What a great experience! It was very refreshing seeing this concept, and definitely one of the most creative.
I loved the skin-taking mechanic. It was a bit hard to understand at first as I thought I have to slice the corpse instead of circling it. However, everything flows nicely otherwise. I especially like how you created distinct characters, not just recolours of each other.
I think the game could benefit a bit with some control refactors: scroll wheel for the scaling is great; however, leaving the right mouse for rotation and giving only one direction slowed down customization by a bit. Maybe giving some of these actions to the keyboard could help?
Great job!
