Right now, you have three enemies. Hurhur the hurbear. Close the door when you see him. Pizza the bird. Put on the mask when you see them. Bunny is just hurhur but he appears on the right door instead of the left. The higher the AI level, the quicker the animatronics move, but on max difficulty, they may all appear at the same time everytime, so I'd say wait a while before changing the AI to 20.
based on fnaf. Also, you may find some easter eggs when hurhur and pizza are in the same room.
