having someone else do it for you is pointless. achieve it yourself or don't.
just keep playing the game and you will learn what parts of the level you need to get better at. i remember spending two whole nights ace'ing all the levels to get the trophy, and i very proud when i finished.
its not that hard, its just VERY frustrating. I think Me and btw05 were talking about this over psn. its really frustrating when you die once, you have to start again. All over again. I tend to give up if I die more than 10 times, then try again the next day.
Although i havent played LBP in a while, im probably gonna try to ace it again next week once i finish savage moon (which is Wayyy better than PJM).
