Fun Fact: Some of the enemies in Kung Fu are completely ridiculous. Martial arts schools apparently excel at teaching kung fu to fire-breathing dragons and bees.
Kung Fu was an early example of enjoying the thrill of having a home version of an arcade game. It was a very simple side-scrolling beat-em-up, but the basic nature of the design belied how challenging it was in the later levels.
Kung Fu was one of the earliest games for the NES, and therefore at one time or another seemed to make its way into the hands of most everyone who owned the system. That shared heritage among NES fans makes Kung Fu an important title in the history of the platform.
