Ok, I said I wouldn't add wavedashing, but I did. x- jump c- airdash v- attack When you jump, you enter "jumpsquat" for .07 seconds, if you let go of x before that time passes, you do a shorthop, and if you press C before that time ends, you can wavedash! Additionally, you can airdash, but that's not quite as cool as wavedashing. The attacking isn't very fleshed out, but it exists, so yeah.
You can perform a super wavedash by airdashing into the ground and wavedashing before the airdash is done.
