THIS should be a video game
I grew up watching the reruns in the early 80s on WNYW 5 (before it became Fox) and god... how I loved it.
If this were made into a game would it be a one on one fighter or a multiplayer brawler?
I think it would succeed as a brawler in that you could fight through various levels fighting regular (but with different designs) ninja, then fight the Elemental ninjas. Maybe throw in references to other Shaw films (or hell, new levels)
