The Game is awesome! Design made perfect!
Gameplay getting boring because it's too easy and your mechanic doesn't grow. Sometimes I had random dices exactly half/half from the start so i just press complete and win. And the items don't actually do anything, yes they give you more damage and hp but it's not really necessary because you never miss half/half. I would add some items which could change dice pull or somehow change a gameplay little bit.
But overall the game is made very professionally!
