Finished the story mode of Mirror's Edge over the weekend. It was a fitting ending, and one obviously left open for a sequel. Given that there have been statements confirming an eventual sequel, it wasn't surprising. But it was properly dramatic and a good end to the admittedly brief story.
I tried going back to do some of the time trial stuff, but I'd really lost my patience. I wanted to get to the end of the story, but falling over and over just to beat the clock doesn't drive me. Maybe I'll go back to it. But probably not. Maybe the sequel will clear up spiking difficulty and sequences of unarmed Faith versus legions of dudes with automatic weapons.
