"The “$ Slide” aka the Waveland – Yes, wavelanding appears to be back (at least in the demo). We called it the money slide because bob$ was the first person to be able to apply it consistently and helped us to actually figure out how to do it. It is NOT done with the airdodge in any way whatsoever. This could EASILY be removed before the actual release of the game, but it’s still in for now. To do the $ slide you have to be in the air (obviously) and do a move that pulls your character in one direction. The best example was Mario’s back air, but it can also be done with his up air (and just to give more examples, bowser’s back air, several of peach’s airials, etc etc). If you do moves like these while you are close to the ground it pulls your character over very quickly and does basically the exact same thing a waveland does in melee. We know that it slides you along the ground, but as far as applications goes that’s up to you guys to discover. If you l cancel the aerial by fast falling first then you do the move it doesn’t even come out and you just go sliding over.
On a side note (something we didn’t really have time to experiment with) it seems like peach would legitimately be able to wavedash back and forth because of this technique combined with the shortened height of float canceling, which means that peach (or somebody else with a double jump cancel, if other characters can do it) will be able to wavedash back and forth quickly"
oh no, we're screwed. peach potentially WAVEDASHING. she is teh brokenz!!!...peace
