You enter the world through a one way entrance. Exit to the left and you enter on the right, fall through the floor and you fall from the ceiling. The only way you may exit is through the one way exit. You saw the one who will end your loneliness use this exit, now you must solve the puzzle of this world to get there. This world is odd, gravity can shift, floors become walls, or walls disappear. This strange world sets the context for Mobius's strange existence.
