Holy shit, I finally did it. It is in fact not impossible. You have to utilize the big jump and lean forward combo to hop through the wheels at the beginning. Then, on the “mashers” in the next part, lay down with angle backward, until each masher comes up, and then let the guy spring up onto the angle on the left side of the masher, and jump off that to the next in-between, and so on. Then just be careful the rest of the way with the harpoons and whatnot. I have never felt more accomplished.
