Got some strong "You are now Possessed"(overall winner of the GMTK jam) vibes from this one, don't really know if you took inspiration from it or not, but anyway this game is GREAT, and those similar mechanics work marvelously on both jam themes. The artwork was beautiful, I liked the music, and level design felt amazing, must have taken a lot of tought/ test to make it work properly. One thing this game lacks however is a menu system, the game opens and already trows the player on level 1, and when you finish, the credits end and take you back to that place again :/. Anyway that's a jam we are talking about and i'm pretty sure you just didn't have the time to do so, also that's a minor detail wich doesn't change the overall experience that I had. Congrats for making this one :D.
PS: It would be a really good addition if you add a level selection menu on post jam version!
