Nice graphics and interesting idea.
There is a lack of feedback when we click on the dice, I expected audio or graphical feedback at least on this main mechanic, this would help understanding that my actions are the ones having an effect on what's going on.
I am still unsure what was happening gameplay wise haha. I seem to have defeated some enemies, but I don't understand the link between my dice result, the damage the enemies take or not, and their dice result and the damage I was taking. I was really confused while trying to play.
For your next one, maybe try to improve on the player feedback.
I also didn't see much of the family theme here, maybe I missed something?
