The possession mechanics were very fun, and I always enjoy an interesting puzzle game. I found the angle of the camera to be a little low, which made some parts a bit hard to see, and it also would be nice to have some indicator of what you are going to possess, since I found it a bit tricky when there was a skeleton and the character close together. It also might be nice if there was some indicator of which buttons were linked to which doors so there is a little less trial and error, but it was a lot of fun!
