Hi,
do you mean the part of the tutorial with those side jumps?
if so, you should be able to either make a walljump or run/dash and jump through.
In the splash screen before the game starts it's possible to change the input buttons, but it probably won't work well on controller since the camera is based on mouse movement which works differently than the analogic on controllers so it might make the camera keep spinning or tilting for example.
There were some things I haven't done with the project and when unity starting their new terms and policy I didn't felt llike continuing with unity, things like making it work properly with controller instead of keyboard and mouse and have a linux version to name a few.
Maybe I could make a godot version though.
