How each character works
Luigi close the door if he is by it by clicking the button And watch out when he is in the center just stare at him until he is gone.
Mario close the door when he is by it by clicking the button
Toad shine the flashlight on him by pressing F key
Yoshi keep the camera on him in the green corner until he goes back in the Gaming Zone
And the Luigi Doll is just part of the background he does nothing
