I enjoyed the game!
Very cool game concept and it kept me hooked to unravel the mysterious contents of the book.
I missed a couple of words on one of the hints and had to "restart" after a bad ending. It would be nice if there was a way to replay an already seen dialogue somehow.
Nice character sprites and good music choice.
One of my favorite entries in the jam!
Edit: Oh yeah and a functional options menu! That's extra points as well!
