That's cool to know the route saves a ton with LOTAD. Must be like 2-3 minutes in a real-time setting or more. Somebody solve 20% please
Speaking of Crossway, I timed the boosting in the tunnel and retimed my Crossway vid since I looked back on it and found improvements to make. gonna just edit the old post for CWay. (spoilers dash wins) You'll hit this gate even if you hit the load trigger early (first pass, not ghosts). Delay boosting for a second and it'll save quite a bit. (it also slows you down after the tunnel, it's just that the slower one hit the bump on the left, which makes it even worse, so I removed it just to time the boosting. Still vastly superior to wait)
for the dash strat you can space your 2nd jump later so you fly into the hole. Also I think L-jumping is faster in the small potion after the dash than morphing and boosting unless you get an instant unmorph consistently.
