Demo yeah? Right after the black out, after picking up the lantern, you can interact with the fireplace for a save point, its a good idea to save there while collecting the books etc. as well.
How many books have you collected up until? From what I can remember, 1 blue book and 1 purple book doesn't count.
If you read the clue on the table, or talk to Mimi, she tells you that you will need to subtract as well.
For all the books you have seen, they are recorded in the recollections tab. So you can count directly from there.
Hey, where are you stuck on?
Yeah it's possible to clear the puzzle, just a bit difficult and requires reading very carefully and understanding the clues
