Can anyone give me hints on how to complete this room? I already got the achievement associated with that room as well as the treasure chest but I haven't completed it. I just acquired the ability to view things in first person but I'm not able to figure it out. I haven't recognized anything I've seen as clues.

Edit: I'm starting to see patterns in the webs. Is that useful?

What is the mayor's house?

Back at the starting village, where you go through the fireplace.
