You don't need that chair rail you say you can't pick up
Others say you can't get the chair piece because banner is hiding it. You don't use that piece. There are 3 others.
Clues would be nice for skulls and green dots. Just play it, you'll eventually get it.
As far as the owl , bat, and house puzzle, I never found a clue ANYWHERE. I went to walkthrough because I wasn't going to waste my time on the endless possibilities.
