I got all the medals except for The Librarian, as I only got 14/15 notes. I'm wondering if the fifteenth one was on the second floor, and I missed it in my panic. But if that's the only thing I'm missing from this game, than that' pretty good.

Some of the puzzles are tiresome at this point, such as the simple batteries + flashlight that all games have. However, this one also had a good amount of new, innovative puzzles, at a decent difficulty level, that made it more enjoyable than other point-n-click horrors.
You should have waited till October to submit this to the Halloween contest! You easily would have won best game! That is unless the third part will be coming out next month? Can't wait till it comes out.
Tip for anyone going for the You Are Safe Now medal: Keep experimenting with the plush toy and ending the game. You'll eventually get it :)
