Based on the anime movie Fist Of The North Star. (Wikipedia, imdb) Flashkof (thats his name) has made an incredible fighter - all done in flash. I was really amazed by the attention to detail in this game, and I'm sure a lot of work went into it. So do me and Flashkof a favour and check it out.
Hokuto No Ken (That's the link - and the japanese title of the movie)
