Super thematic and the art is fantastic. The state mechanic is very cool, lots of potential.
When starting a new game, I didn't even realize at first that I was in a playable part of the game because the lighting was just a little too dark and I couldn't see really anything, including the player character.
It's a little inconvenient that the player character continues to look to the mouse when you try to activate one of the states. Possibly a key to activate the current state would work better?
