I thought that when the game clicked it was absolutely brilliant but it was let down by some infuriating flaws that seemed to kick your arse at random points. Sometimes you can make the most difficult of jumps and clear a section of jumps/climbs/wall runs perfectly, while other times Eve failed to grasp a ledge or run up a wall because the angle was slightly,
slightly off.
I really enjoyed how the game is tailored so that you don't have to use the guns but they are there as an option if needed. It's not a FPS nor should it be played like one. The hand to hand combat was good but you do have to have good reactions to really get the most out of it and the same can be said of the free running too. There are times that the level design and free running can be a major chore (the sewers for example) and the game can really test your patience.
The Time Trials and Speed Runs really do test your skills so if the main game annoyed you then I'd avoid them unless you want to get the Trophies/Achievements.
EA should be applauded for even trying something like Mirror's Edge though. I hope there is a sequel with refined controls and a little more variation between levels. It's one of my favourite games of this gen despite the flaws.
