Love the visual style, fantastic looking game. Controls are good too and the body switching works great, I enjoyed trying to optimise my play by swithing to enemies that are out of detection range so I didnt have to fight them. I would say that the skeletons feel like they can't be killed by sword (but that may just be me not being good enough lol).
Excellent work, you could certainly expand on this concept if you wished, would be fun.
