From what I've heard, they purposely made the combat kind of wonky in Mirror's Edge so that people wouldn't rely on it. Although they did say that the combat is being fixed for the sequel, so that kind of makes me wonder if it was intentional or not. I didn't pay too much attention to the recent Steam sale, so I must have missed Mirror's Edge being listed. It's not a big deal either way, it's only $20.
Ubisoft also has their name on the No More Heroes games. I really liked the first one, still waiting to play No More Heroes 2.
