From what I can see this looks a really decent parkour mod.
However I noticed a little graphical bug that happens when i have shaders turned on, some areas flashing in two different colors.
This is actually caused by two faces overlapping eachother and the graphics engine not knowing how to handle it prober.
There's actually an easy way to completely fix it. You just have to make one of the two overlapping objects .01 smaller so it moves the face behind the other.
