Hi, I'm sorry if this has already been posted elsewhere, but I'm trying like crazy to avoid spoilers for this game. I just got this game yesterday, and I'm going mad trying to find puzzle 012. Does it even exist? I was also wondering if it's possible to completely miss a puzzle, and not be able to go back and find it later. Also, it seems weird that puzzle 110 is mixed in the same room as much lower puzzle numbers.
