I found a wierd exploit of the wallrun mechanic, its on the V-Slice level near the finish and I show you where in the Video:
Instructions to Recreate:
1: Find a corner that has an angle smaller than 90
2: Begin a wallrun away from the corner
3: Jump & Turn around on the same wall then hold W+D/A
4: Once in the corner spam Jump
