Introducing, The Wavedash.
It's SSBM wavedashing, but better.
To perform a wavedash, all you have to do is basically jump and airdodge at the same time while holding diagonally down. The tech can be buffered by just holding down shield and mashing jump.
You can jump, shield, grab, or perform any grounded move almost immediately after wavedashing. You can even chain multiple wavedashes together.
Every character has a unique wavedash distance. And the distance of a wavedash can be either increased or decreased depending on your stick input.
You can also perform a "waveland" by airdodging into the ground before you land.
It's also worth mentioning that any character who can jump cancel their attacks can wavedash out of them.
That's pretty much all of the things I know and all of the things I discovered while experimenting with this new tech. That's it for now. Enjoy sliding around!
