Quite a fun game. Some feedback:
1) At one point while performing dice selection, the game switched the cursor to one of the dice and wouldn't switch back until I was back in the map.
2) Being able to keep dice between turns renders defense resets less relevant. Though possibly this is a bug; dragging attacks onto enemies stopped working the first time I did this.
3) Most rows of the map are identical. So, selecting a path feels a bit pointless. Mind you, maybe I just got a bad run.
4) It should be possible to throw a die even if another die is already being rolled. As is, waiting for rolls feels a bit slow.
