Love the atmosphere and audio. I like the combination of the turn-based mechanic with the feel of an exploration RPG. I quite enjoyed the upgrade system, although I'd want the ability to skip them if I'm happy with my setup.
For just a game jam version, this was a great experience. For a potentially full version, I'd say this is currently lacking just a bit of motivation of curiosity to pull me in further. The gameplay is fun, but it should tease a bit more about why I'd want to explore these caves, what could be down the next ladder if I just keep going.
Potential bug: it froze for quite a while after I claimed the Leftovers item upon clearing the second room. It did keep playing, but it paused for like a solid 10-20 seconds.
