It took me a second to figure out that I have to hit enemies with the dice to do damage, but once I did, it was really fun. There's something about hurling many-sided polyhedrals around that makes me happy. Loved the art and the music as well; set up a great atmosphere.
I would have liked to see some more interesting variation in the skills for each character. Other than throw distance and damage variations, they play mostly the same. E.g. maybe an AoE type attack could be a 2d4 rather than 1d8 or whatever, to give more chances of hitting multiple enemies.
Anyway, for a 48-hour game, this looks and plays great. Well done!
