The places that neither give you hints nor items:
-The bathroom
-The burner room
-Either statue
-The hallway to the basement (of course, you still have to use it)
-Tiny portrait of the house in the stairwell
-The two windows and weather gauge in the upstairs landing
-The room with the screw, 6 outlets, and what looks like a trap door
Like if this helped you.^ Wish I hadn't wasted my time clicking everything in these places.
