Hey! I'll take some time to write a proper reply, but you can toggle off tutorials and those confirmation menus in the options.
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.
