Some side thoughts:
1. I have over 200 books! It's getting tedious to scrap them all, I want a way to bulk scrap them. Maybe make the books stackable?
By the way, I think some inventory sorting function could be useful, so things are in standard order and not change when I use up something and gain more later.
2. With about 100 maps explored, the selection screen is getting cluttered. Now I really want a way to delete old locations.
3. When exploring in the mines, I have an idea: When muffled, the character can use an action to make noise (like knocking the ground), so the centipedes are attracted together while I quietly move to another position, then I can use a single potion to kill a group of them.
4. About Verdant sandals:
This equipment is useless outside of setting forest fires. And even when I'm using it to prepare a forest fire, it's still inconvenient to use.
I think it should inherit the nettle protection from tall boots, as provided by verdant blessing.
If it needs to be buffed, then either give it better utility for preparing the fire, or give it some other utility.
For preparing the fire, it could either be buffed to grow tall grass in a larger range (3x3), or be able to overwrite non-flammable plants like spearmints and foxgloves.
For other utility, it could give hp recovery. Maybe heal 1 hp for every tile of tall grass planted. If that's too much, you can make it heal with a probability.
5. Roses hurt!
Currently rose deal 1 damage when passing through, and no equipment can block this damage. The pathfinder also doesn't try to avoid it. I think this needs to be fixed, either make tall boots block that damage, or make the pathfinder avoid it.
