Obnoxious control-scheme turns an otherwise entertaining game into an exercise in aggravation.
The most frustrating part of Rag Doll Kung Fu also happens to be it's main gimmick, which is the ability to rotate your character's arms around 360-degrees using the sixaxis. The controls are so imprecise (unless you're one of the sad children who's dedicated their life to playing it, so you can upload videos to YouTube), that it simply becomes punishing to watch as you constantly throw lightening balls, punches, and kicks which JUST miss their intended targets.
Even worse is attempting to grab and swing from ledges. You'd probably have more success playing a game of lawn-darts, blindfolded.
This might not be that big a deal, if precision weren't required to beat most of the game's "challenges." Some of the challenges are entertaining, some are annoying, and some are downright punishing (in particular, the challenge which requires you to air-juggle an enemy with lightening balls for an extended period of time).
Ultimately, this game isn't worth the $10 price tag. Honestly, it's not even really worth the time at the price of "free."
