Woop, this was cool! Having tinkered with Twine recently, I'm kinda blow away by what you put together and managed to do it all in a weekend.
I gave this a few tries but couldn't get the third and (I assume) final item. I really liked that the place names were randomised, that felt like a pleasant surprise the second time I started a run. Also the mimic was such a nice touch!
One gripe that kept me starting more runs was feeling limited during combat. One engaged it's pretty much a fight to the death (unless you're stacked with potions, which I found unlikely). I wondered if allowing some kind of "flee" option would help this, but this only helps if you have enough $ to afford a potion and start a dungeon again.
It's funny that in the devlog you mentioned rushing the enemy art and yet those felt pretty endearing to me :)
