Here's a playlist of completing all the Carkour tracks.
I must say I enjoyed myself trying to complete these and have to admit, Nightmare is worthy of its name
Damn Polar! Nice one. You're the first person to finish the LoopGap nightmare course, as far as I know. Shoot me a PM and I'll send you a steam key as a prize
Glad you like the Carkour stuff. I had fun making the maps
