Assassin's ulcers

I bought AC2 a little while ago (I'd heard too many bad things about the controls in AC1, so figured I'd try it later).
I have a lot of fun with the game as a whole, but it also drives me completely batty sometimes.

My sister can't stand to watch me play lol
OTL;;

_{I wish my computer could handle it. :< I wonder if certain controls would be easier on a PC rather than a PS3.}
