Thank you for your feedback and I'm glad you enjoyed the game !
I admit the diagram hint was not the best thing to do, the player could easily deduce the solution to the second torch puzzle without using it, and they could get confused thinking it's related to some other puzzle. I made sure to correct that in the post jam version.
For the item selection, it's something I'm really proud of even though it's very basic, because this was my first time creating a customized UI on RPG Maker, and it took a lot of trial and error to get it working. Together with the puzzles, they made me learn a lot of mechanics on the engine, and I'm very glad people liked it.
