Today I made some more testing about wall ride.
I made a new quick video with 3 layout, cause I figured the last video was way too long.
At the end of it about 2:10 after the screen explosion the last three wall ride are in reverse, and after some testing I realize that the Dnano climb much better in reverse than forward, well it's just hard to keep it on track.
Anyway here's the video:
