This is pretty cool! I'm impressed with how much there is, and I especially like the animations, just the idle animations alone make this game come alive!
My only concern would be the difficulty of the game, but this can often be mitigated the more you play and learn the best strategies.
The dice upgrades is a really cool concept! The tooltips on enemies is a nice addition, tooltips on dice might've been nice too, though there's only so much we can do with such a short amount of time.
