Yeah, I watched some of Prilts videos. He is absolutely amazing at Mirror's Edge. Most of these trials I only got three stars by a couple of seconds. I believe he goes by Ovendonkey on youtube and he does some good tutorials aswell, which I used. One of the DLC tracks which is called Kinetic I'm 30 in the world on the leaderboard. I think I'm above his score there, I'm pretty sure I am. Not to brag.
Just to let you know, I have 100% on Mirror's Edge and all 99 stars. It's actually not that hard. It took me a long time though. Just letting you know it isn't impossible. Also, if you want to know how I did it, I watched videos on youtube of speedruns, I also looked for shortcuts and tricks I could do to go faster. I searched the level thoroughly before playing through it properly and after that it is just a lot of trial and error. Good luck!
sorry man, i usually pay attention on it and you can find around full of posts of mines which have been edited coz i forgot about something... otherwise i can't say i never double posted, btw i'll try to pay even more attention about that
