I had initially written about Mirror's Edge over a year ago, having played its demo fresh out at the time. I decided not to get it at release after some mixed reviews. But I found a used copy on the cheap, and decided to give it a fair shake.
I'm having fun, but it's certainly at a cost. There are sections that are really tough, especially where guys are shooting at you. It feels deeply unfair that all you can do is run away as five guys mow you down with shotguns. The particular shotgun section took me a good twenty tries to finish, and try as I might I could not get past without killing them, which I feel is a little contrary to how the game works.
However, during the complicated platforming across rooftops, the game is a blast. Especially the time trials, the feeling of racing from building to building is a lot of fun. The sense of speed and danger is in your face, and each fall and failure due to oncoming train is a real jolt.
I probably would have been a little miffed buying this game for full price, especially given its relatively short story mode, but at a bargain price, it's worth plowing through some of the frustrating parts to get to those great expanses of uninhabited rooftops.
