I love that all the characters are minis. It both keeps with a consistent style and also probably saved a lot of time on animations!
The dice cascade as the game goes on where a ton of goblin spawning D6s spew out was also really fun.
I think the smoke effect on the weapon probably could've been toned down a bit. Maybe adding some random variation on the speed of the smoke would break up the very clear "waves" the effect creates when you are shooting.
