A cute bit in Mirror’s Edge: at one point you’re in a janitor’s closet, complete with a diploma on the wall he’s made for himself, and his pet rat. He also seems to be puzzling over why so many red doors are getting busted. (Objectives are marked in red, and you open doors by kicking them in.) A bit later you see a room with a supply of red doors.
I think I’m almost done with the game. I replayed it– it’s amazing how much faster the chapters go on a second run– and I have at least one star on all but two races. I think I’m probably not the three-star type. It’s fun to whittle down times and learn to do moves routinely that were huge challenges at first; but to get three stars you have to do everything perfectly, and that’s more frustrating than fun.
