Touch Arcade - Alright. iOS games and video games in general can push the boundaries of good taste, and a game about running around and knifing people to death certainly sounds pretty messed up on paper. But seriously, look how cute that icon is for Knife That Guy [$0.99]. That is one adorable psychopathic killer, am I right? The rest of Knife That Guy's visuals follow suit, and create a game about killing that's not so much offensive as it is twisted and disturbing. I can totally do twisted and disturbing.
