It's impressive how much you packed into a jam game!
The graphics were charming. The atmosphere was great. I liked the variety of items and enemies. The different biomes were a neat addition and each introduced their own complications to worry about, keeping things fresh.
I played several games, and found it quite challenging.
My best runs were the ones where I got lucky with finding food and focused on rushing for the exit each round. The few enemies I killed didn't drop anything or seem to give any reward other than points, so I avoided combat as much as possible.
The longest I survived was up to round 9. Most of the time, I lost to starvation or after aggroing bandits, who are terrifying and relentless. In my experience, you can't outrun them, even if hydrated, so if you're being chased by one while unarmed, your only practical option is to find and escape through the exit. It seems like water doesn't even slow them down like it does the player. All that said, I suppose enemies are easy enough to avoid if you pay attention to the minimap.
I got caught in doorways and stairs a lot and I think item spawns could be increased, but you've already addressed that feedback in other comments. Also, a minor nitpick, but I'd like to be able to pick up items from slightly further away.
That aside, the foundation of the game is very solid. There's quite a bit of depth to the game. Again, the polish put into this is very impressive for a jam submission. I don't know if I've ever seen a jam game have an options menu. And your footsteps sound different depending on what you're walking on!
I had fun playing this. Great job!
