Syncs on 0.9.11.
Easy to tie, will be significantly less trivial to break it. I spent zero effort on the boost, so that will likely be the path to take for optimization.
The more frames you spend holding up-right after the fall, the higher the angle is, but the better your speed. I chose the sharpest angle but couldn't get a 08 with this boost&fall.
Syncs on 0.9.9. The same baseline: boost, fall fast, glitch bounce, sidegoal. The difference is we sidegoal off the left rather than the right, which is faster because the distance we have to travel between the bounce and sidegoal is lower. Now it's .90!
