We all know how bloated the config menu is (as in 60 configurable controls) and 3/4 of them are absolutely useless. so i did the liberty to test every single config to see what works and what doesn't.

lets start with the configs that 99% of people want to see.
Horizontal +
right

Horizontal -
left

Vertical +
Up

Vertical -
Down

Fire 1
Punches

Fire 2
Kicks

Jump
well jumps obviously

Fire S
in the files is Super Attack which is the attack that uses the bar

Start +
pauses the game

Roll +
Dodges in the way the character looks

OK
its select without saying select

M
this one is unbinded and it mutes the music in all levels besides the tutorial level

Kick up
this one was surprising to me that is also an unbinded move that has an alternate kick that you well kick up

That's all of them, yes only 13 out of 60 configs that is ~22% that actually does something, and for the 1% who ever wants to know what the other 47 configs are here you go.

As you see a lot of them are dupes or straight up anomalies but anyways that's all of the configs within the unity launcher. Don't ask why i don't got a clue what's with the bloated config menu. If i had to guess it was the dev being fed up with people complaining about the controls then gave us this, but you still can't change the controls for controller for some reason? i am guessing its unity being unity at that point, hope this helps with your configuration of your controls.
