The game is a third person game, so the camera rotates around the player character just like it does when you play the game on your monitor. Maybe that seems like inverted to you. vorpX cannot change the actual gameplay.
Third person games usually are best played in immersive screen mode with a rather low head tracking sensitivity, essentially creating the (not perfect) illusion of being able to look around freely to a degree. Can’t remember 100%, but that should be the default setup for the game.
