well you know riolu could've been my favorite part above bas and osaka's if these ramps were placed on the right spot.
at that last drop part onto the shack than onto the ramps infront of the finish. these ramps were placed to close to the shack making the drop unsmooth. if they were placed a bit further they would perfectly work from all angles.
I tried to drive that part from all possible angles and it always ended up being unsmooth. (so I opened the editor and solved this by placing them a bit further away ) anyways dunno if thats what he meant to do or not
anyways building a new valley map
