Yes, I've been doing all that stuff for awhile now =P
But I didn't get there overnight, that's for sure.
I've only been playing competitively for one year, so I'm not as good as I'm going to get yet.
Multimoonwalking with Peach is relatively easy for me, but that's because I spent a long while perfecting my moonwalk.
I can moonwalk in real life as well, but that's beside the point XD
My tech skill is near SW, but it's not AT his level.
I can do a lot of stuff with Ness, possibly everything humanly possible, but I struggle slightly with float canceling with Peach.
Still, 2x speed illusion stalls are easy once you get the timing.
I can also do that with Falco, but it's difficult (his normal stall is almost as hard as Fox's 1.5 speed illusion stall, if not equal to >_>).
Super Wavedashing with Samus is somewhat difficult, but only because I have to get used to the rhythm of the button inputs.
I've gotten 4 in a row, back and forth, canceling the slide as fast as I could with downB to start over again.
Yeah, I'm really different from all of the other 15-year-olds ._.
