Great game! I love these type of games, I remember I even made a very similar game once in scratch, it had like exactly the same style lol.
But I still couldn't beat it yet, I am stuck on the books puzzle. I've just realised there are many pages in each book, which just confused me even more lol, so please, give me a hint😭
But so far, puzzles are very creative, interesting and unique. Very nice game, good job!
Also, sounds would add a lot of immersion, like rain sounds or music, but the jam is very short so I understand.
