Awesome concept, and I really like the art and story, the dungeon looked great and I was excited to be exploring and exploding chickens with lightning bolts.
Unfortunately, I never quite understood the combat. I've played yahtzee where you can put aside some dice and reroll others but I didn't see this option here. I didn't really know what the runecards do, I guess give specific bonuses and starting dice requirements but overall I just couldn't pin it down. Full house didn't work with color apparently either (3 blue 2 red for example). I think I randomly took damage and healed the enemies as well. I'm not sure if these are actually bugs, but might just be me misunderstanding the combat mechanics. Also, the first enemy I fought had 150 HP which I struggled with, then encountered a 45k hp monster. A massive difficulty spike. Also, I think the big page pulling up mid combat to calculated all the bonuses is not needed, it should be a quick flash on the screen to not break up the combat pacing.
Overall, this had huge potential it just needs some more explanation on how the combat actually works. I recorded my gameplay here
