Really liked the concept! Sadly I wasn't able to finish it, I got stuck in that one room with a bunch of mushrooms and couldn't find a way to open the door.
Overall the game is cool, however would have liked a bit more explanation on what each power does, specially regarding to opening or interacting with the enviroment, by the end i didn't understand if only ghosts could open chest or if we could aswell.
Both the artstyle and music were pretty good good job on those!
