Favorite game of the Jam. You should make it a full blown steam release with new dice, new enemies, new bosses, and a lot more levels instead of 20. You should have more upgrades like being able to play more than 3 dice in a turn. You could have save points in the game so you don't have to get so close and lose right before the end. You could also introduce a hard mode which is the same game without save points.
