Rag Doll Kung Fu is an unusual fighting game, designed to be played completely with mouse-cursor input. Players control their combatants with clicks and drags that cause limbs to swing and move. The game was created as an recreational side-project by Lionhead Studios artist Mark Healey, who describes the action as "a kung fu fight with string puppets in which you don't have to worry about getting the strings tangled up or even having a kung fu fight at all if you don't feel like it." Originally available exclusively through Valve's "Steam" digital distribution service, a retail-boxed version of the game comes from independent-minded publisher Merscom.
