Interesting find. It's not really the same at all though. That game is basically just making up stuff as you go along with no rules whatsoever. I really would like to see Bragging and Fighting developed one way or another.
In case this doesn't make it into a computer game you should seriously considering making a real card game out of it. Sounds very much like something Steve Jackson Games (e.g. Munchkin) would do. It is a super fun concept.
