Really cool concept, weighing up how many boosts to add to your roll is fun. I think if the player rolled more than one dice per round it would be even more strategic as then they could aim to get both an attack and a defence while also boosting both? Just thinking about that makes me a excited haha, I really hope you continue work on this after the jam.
Gorgeous pixel art, really crisp and nice with perfect colour choices. The enemies being different sized die was also a very witty addition and how each of them was turned into an enemy was very fun and creative. My one issue with the presentation was I wish attacks had more feedback/juice.
Wonderful work, really hope you keep updating post-jam!
