I'm not sure this Mod will be as Successful as most see it to be...
It most likely won't work. Either buy Mirror's Edge for the PC or go out and Parkour in real life. Trust me, it's alot more fun than sitting at your desk when you leave the hardest Hurdle for last, then you find out you can't accomplish it. Once that happens, Boom. The mod's over, and after alot of hard work.
My suggestion if you continue work with The Parkour Project, is do the hardest parts first. If they are impossible, find a way around it, a way to abandon it or just abandon the entire project altogether. I guarantee the Parts you can't leave out will be the hardest.
In the unlikely occasion that this does work, well I might add, then I would definitely be the first one to test it :P - Besides, I think the Parkour Style I displayed in my Parkour Challenge and Deathmatch was good enough, I don't think we need an all-out Physics Revamp.
