Very great game. I had a blast playing it !
The atmosphere especially is fantastic
The only criticism I would have is that it would be nice to be able to leave the stones on the door in the final puzzle (while you check the different hints) but it wasn't a major problem either
You misfiled the fields for the jam though - the game page indicates that you did everything yourself, but the question for the jam submission is what did you NOT make from scratch during the jam
