I think this is a very clever concept.
I love your art style and this combined with these scene transitions really make a scary atmosphere. I especially like this idea, that the eye and the hand have different hitboxes so that the one can only go there and the other one has to take the log way.
Another strong point of your game is that you introduced the two unique abilities step by step so I had no problems following along, even after the throwing thing.
I find it very nice that you included checkpoints because otherwise it would be very tilting to start a big level every time from the beginning.
All in all a very unique concept and very good work! Nothing to criticize.
