Oops, you're right. Fixed.

> I don't have experience with pen and paper RPGs, but how does this compare with other "ultra-light" RPGs like Risus?

I have been asked the same by SDF bboarders, but I honestly cannot given an answer (yet)—I need to check out Risus (and other systems).

> And is this setting agnostic?

Yeah, there are also different skill sets. I have added magic because fantasy themes seems to be the most popular settings, but I plan to add different ideas for modern-day or Sci-Fi scenarios, such as rules for hacking systems, space maneuvering and space ship battles, etc.
