Beautiful art and animation. I managed to get the two ghosts, but the exit was barring me from getting to the exit.
Neat that your previous ghosts can kill you (and they killed me a lot trying to get the second one). Not only did I need to stand in place pre-ghost, but I needed to move predictably so I wouldn't hurt my future self.
Listened to the youtube you provided. It's so good. Suits the game well.
