The level of polish is crazy, one of the best so far!
I have finished it twice an still have problem understanding what does what, except for the obvious... I couldn't tell if the cooldowns were faster with the speedy dice, couldn't see what the heavy dice or strong launcher does, I tough the double dice would double the number of dices I throw but didn't really see that. Also some balance issues, I couldn't really find a better strategy than black explosion + shrapnel and hold the 2 mouse buttons down, the others have too long cooldowns and the big dice effects didn't seem to impact the gameplay.
However, this was super fun to play and amazingly executed graphically, with the sound design and the gameplay loop, fantastic job!
