I'm glad that you and others like the art!
Yeah, I tried to implement simple 1 2 3 4 ... hotkeys and there is in this build, but it's bugged so it isn't usable.
I'll let you in on a tiny secret though: The movement dice are rigged in your favour, when you are more than 2 tiles away from the closest enemy, there is a 40% chance each movement dice will point towards the enemy, I added this system because before that it was much worse than it is now.
