Main game:
This is so less people complain about rotation being on both joysticks, despite them just being able to swap the inputs themselves before this.
I think people just don't generally know about SteamVR input or something because this has been a recurring thing for months :p
The default expected mapping for Climbey used to be rotation on both joysticks, grip and controller moving for walking.
People generally expect joystick walking for some reason despite it being a lot less comfortable and nice, so I've swapped the input mapping so rotation is only on the left hand and walking is on the right, which I already made a default choice for in the SteamVR Input binding screen years ago.
