Fantastic altogether. UI is great, tutorial explains mechanics perfectly, gameplay loop is solid and I haven't seen a single mistake in generating map. I was pleasantly surprised by friendly fire between enemies, good mechanic, encourages playing with positioning.
Suggestions:
During tutorial I've had trouble telling what things on the ground are meant to be picked up, some shimmer could help.
It might be because I'm fresh off poe, but the game feels extremely slow. In the end of the day it's a personal preference, but damn, it made both combat and exploration feel very sluggish.
Still it's easily one of the best games I've played this DD. (It's the first one, but I'm sure it'll remain at the top)
