Yeah I know the game needs better tutorials and stuff, I kind of threw you in there huh? The left hand is an EMF reader and it was to help you detect where the ghosts are without swapping between realms all the time and guessing where they might be. Obviously, this is info that should be in the game and conveyed to the player so I know that's something to work on.
Either way I'm glad you thought it was interesting and fun! Thank you for the feedback!
