My main tip is to keep airtime as low as possible and make as little use of the homing attack as possible, in the section where I use the boost pads to basicly skip a section it is quite hard to get consistent result(you can make it to the springs in one leap in the optimum case) i actually just lucked out on being able to quickly land on the platform and reach the springs, so it is just trial and error for that.
But in the end you just have to pray that the springs in the last section don‘t mess you up by canceling all of your momentum.(i mean the set of two with the row of spikes in between before the video cut).
I wish you good luck with trying to beat my time and fun with the game.
