Not sure. I feel like I solved the majority of the puzzles (only the coat of arms and combination lock were left). I solved the candle puzzle, got a yellow flash, and heard something move. But nothign in the room appeared to change and nothing was added to my inventory. I spent five or so minutes clicking around on various items but nothing reacted....

Can not read notes, because inventory slot blocks them.

Whilst playing around with video settings I ticked the VSync box. It appears to have permanently set the game in portrait mode. If I restart the game it restarts in portrait mode. There appears to be no way to reset this.
