Santa Fu is a holiday-themed remake of Kung Fu Master, where players take on the role of St. Nick who is on a quest to spread festive joy by beating up elves, reindeers and gingerbread men. There are five levels to play and two hidden characters to unlock, although both of them have the same set of moves as Santa Claus and differ only in appearances.

The responsiveness of the controls can be a bit dodgy at times, but to counter this problem the developers have also made the game available as a free download from their site.
