The system was a little confusing at first before reading the tutorial, but after that it is quite fun and strategic. Holding the dice after you roll them and buying more rerolls is a nice touch that gives the player more agency. The graphics also have a very cohesive style.
There seems to be a bug (at least in the Windows version) where you can only open the shop once at each level you reach and the shop, rest, and recruit buttons duplicate when you level up. Although choosing to rest/upgrade early vs risking your party for later does add an extra layer of strategy. A restart option after game over would be nice.
