I think what Pedro's getting at is that the mechanics were universally cited as problematic in Mirror's Edge. The 'Parkour game that keeps trying to be a FPS for no good reason' problem.
Since there has been ALOT of argument about it, and the debate has come and gone, it's important to come down critically reasoned on one side or the other, and back up your reason. Because everybody knows about the promise of this game, the exhilarating headlong rush. The game didn't quite deliver on that promise.
You should also read the reveiws on site of this game, because if your aim is to be published, then you're writing a second opinion piece.. which is easier because you dont have to do so much exposition about the gameplay-
but it's harder because you have to find a center for your piece that's strong, which is hard when it's already been written about!
PS I would like to see you get published here- you are a good writer!
