"I found myself with duplicate permanent dice a few times" What I take away from that is that you played multiple runs, so I'm happy. There were a bunch of design stuff I could've improved and implemented. Preventing permanent dice from clogging your inventory is definitely one of them. Good suggestion

Yup, I died once on the final fight and my completionist brain wouldn't let me move on until I had beaten it, so I went through again and used what I learned from the first run to advance much more tactically. Actually getting a game over I felt like was entirely my fault has been pretty rare for this jam, hence the props on a great difficulty curve. :)
