Oh, great to know, amazing inclusion! :D It was only a slight bother in the end!
Hey, thanks for the detailed feedback!
Color coding the classes was very difficult (because I kept running out of colors from my usual palette), but I'll be sure to brighten up the darker ones.
For the dice overlapping, you can toggle "sort dice after rolling" in the options.
Thanks for the tip about the particle effects too. I'll add that later to improve web performance.
