I really like this mechanic! Fun to see a fast paced, hectic, decision-making style game. Gives you a bit of the same satisfaction as throwing a bunch of dice in a board game like risk or axis and allies. The AI is a pretty good challenge as well.
Things to improve:
The drag+drop mechanism for choosing actions is a bit clunky, especially since dice obscure one another.
UX wise, I feel like the order the dice layer over one another is a bit backwards: it felt like the dice were trying to hide.
