Rush is the entity that comes around door 10. You must hide in a closet or under a bed to avoid it. Or by staying out of sight. Ambush comes around door 70-80, it is like rush but goes back and fourth for 3-6 times. You must enter and exit the closet multiple times to avoid it. Seek appears around door 30, you must run away as the light guides you! Figure comes at a Library at door 50 and 100. Collect books with shapes on them and "figure" out the code with a paper on the desk!
