Thanks for the comment, That mean a lot to us!
When you receive new dice, you will be able to spam the dice bullets through Q, W, E and R buttons. It should show the dice's details you have at the HUD on the left side (It also tells the ammo counter), but when we made the build, it turned out that the HUD was not working.
I was trying to fix that bug until the last minute, but I still can't make it in time (The new dice are also shooting at normal 1d6 same all).
