This is an extremely unique take on the theme, and damn the visuals look really stylistic and just pleasing to the eye in general. You established a really good atmosphere here, and the music goes perfectly with the artwork. You had some good use of sound effects, and the animations were really well done.
I did have one problem though where I thought I got softlocked because one soul was taken and the others didn't move at all, so I could only close and reopen the game. You might also want to consider making some sort of tutorial level that would walk you through the game's mechanics instead of memorizing text on the title screen (I thought the hands were just part of the environment haha).
All in all this is a really stylish submission and a good take on the theme. Great job!
