Oh goodness, thank you so much for finding and posting this! That's a huge honor.
So we have a particular route we've labbed and ironed out to get through the tree level at the end. This video here is a big comprehensive step by step breakdown of it with why you're doing what you're doing and why the game's doing what it's doing at every turn, plus an explanation of how the otherwise hard-to-control forward momentum works when coming off those bounces.
We don't know of anyone else who's labbed the game to this extent, and this is just us sharing what we've found. We make zero promises that this is the route. We're not aware of a faster route, but that doesn't mean one doesn't exist. Maybe you can take this video as a starting point and figure out a way to put your own refinements on it from there. :) Hope it helps, whatever you choose to do with it!
