Game is actually fun and addictive. I like it when jam games keep your interest and make you play them through. Loved your approach on the theme. Placing buffs on your dice is pretty neat concept. Visuals are fantastic and audio design is good.
Few minor downsides are:
Absence of pathfinding, enemies get stuck in the walls. Also, spawnrate doesn't increase overtime. So you're often wondering around searching someone to fight
But overall you did a good job, congrats finishing that in 50 hrs!
