Pretty difficult game, but a lot of fun and pretty fleshed out for a jam game. The concept is really unique and I think it has a ton of potential. Good job.
I would love to see the idea made into a full game. That said one thing for me is that I think the death mechanic needs to be a little less frustrating. Not that it can’t be difficult, but the sanity meter would drain pretty fast and it really feels like by the end you are fighting against your character’s life battery and not like overcoming the dungeon.
