INPUTS:
d(short tap)--w+q(hold)--w(slide to) s(hold)--(slide from Q) a--w(hold)
or
a(short tap)--w+e(hold)--w(slide to) s(hold)---(slide from E) d--w(hold)
(Remember to let go of S as you land or you will brake!)
Keep trying and you'll get it! It's mostly about cancelling fast and timing the inputs well (the double jump especially). Good luck, hope this helps!
