Did anyone else's game do a glitch on the puzzle that was in the secret part of the library? Mine kept glitching.

will the game return?

How does it run?

Seriously - HOW - do I figure out the bookshelf puzzle?? I'm not satisfied with just an answer, I want the logic behind it before I can move on with the game!

There are numerous clues which have to be remembered to solve the puzzles. I wish there was a way to save a clue. I tried the screenshot option F12 which works fine but to to view the screenshots I have to Exit the game view the screenshots in Steam and then open the game again which is just a hassle. I wish there was a camera in the game. Some games have this option and the camera shots can be viewed while playing. This is very convenient. Any suggestions would be appreciated. Thanks. Marc....
