Love the visual presentation here - the rolling dice physics and the pixel UI have a lot of charm, and the "sum of dice + bonus damage" ability design (Crimson Slash, Sapphire Barrier) sounds like a fun system on paper. I have to admit I struggled to figure out how to actually spend the rolled dice on an ability even after trying several drag/tap combinations, so I may be missing something obvious - a quick on-screen hint for how to assign dice to a card would help a lot for first-time players like me.
