Wow this was super duper fun! I ended up playing a lot longer than I intended to but I think you have a great couple mechanics working very well together here. The UI had a few bugs here and there but with some touch ups and polish (and added music) this would be absolutely perfect!

I'm not sure what triggered the bug, but there were a couple times the number dice weren't matching up with the layout of the UI (always happened at the start of a new round/enemy). I had a couple times where a number dice started in one of the attack slots, and one time where I thought I was missing a number dice entirely only to find out later that two of them were layered on top of each other.
