I like the graphics and the way you need a certain number on the dice roll to use specific cards. The tutorial was clear and simple, easy to understand.
Every time an enemy attacked I couldn't always read what the enemy was doing, because the information disappeared too quickly.
I think there should be a limit to how many times you can use certain cards and also maybe have a currency, so the player will have to choose what cards to spend it on. (Just a suggestion)
Overall a cool idea which fits the theme nicely.
