It looks very good and consistent. I wish there would have been some sounds or music.
It seems that the dice rolling is kind of tacked on, and didn't seem to be a main feature. You gotta kill enough to get some money, to spend to get dice, to be able to roll big nukes. But taking your mouse off the attack to get the nukes makes it so that you surely get attacked. I found it hard to both pay attention to rolling the dice on the side and dodging the enemies. And when the mouse is taken off of the dice rolling to attack, that window goes away anyway, so you cannot use the nuke.
It would have also been nice to see some more uses of the dice or store - a better use for the money. I survived for like 4 minutes just melee attacking the enemies and didn't even need the dice itself. Also, some variety of enemies would be nice too. Maybe even just different colors of enemies, or sizes even.
