Very nice! I had a similar experience with the bugs - small things here and there mostly. Text became "New Text" after I restarted a game, I was told there is no thief in the party when checking for traps on a test but Lupin had 39 health, stairs let me walk in, little stuff like that. Overall I think you've got good bones here. I really like the dungeon itself, it feels immersive and looks and sounds really good. I'm jealous of the water drip sounds, I want them in my game. This is a place I really want to explore. I also love cooking and crafting mechanics so I'm glad you added that.
I couldn't figure out how to heal (I think the potions are bugged) so I wasn't able to get very far after 4 playthroughs. It feels to me like a few tweaks here and there and the whole game would come together, but that's game jams for you. I think with some bug fixing and polish you should be able to re-use the core of this as an engine and hit the ground running next year. I'd also like to revisit this one if you make a post jam release.
As for movement speed and combat difficulty my thoughts are the same as other people that posted. Lighter and faster so I can see more of the dungeon.
Overall it's good, well done!
