Rolls xD6 and adds stat bonuses automatically, which is nice.
Roll button is smaller than need be, given that post-stat entry it's likely the only bit of the UI that will be engaged. Doesn't allow for negative stat values, which is too bad. More than 2 D6s can be rolled, but there's no "choose the highest/lowest two" option. I had issues getting it to reliably open via Android with the DuckDuckGo browser (most Android compatible itch things load okay, historically)
Functional, with a neat graphical layout.
