I figured out how to get the game working for WMR users.hey thanks for telling me, I was actually scared it might be my controllers.
If you search in the game folder for a file called "bindings_holographic_controller.json" and also "bindings_vive_controller.json" you can copy everything from the vive controller .json file and paste it into the holographic controller file.
It seems the dev's didn't even plan to include WMR support to begin with given their config for the file it uses is practically blank.
