Moss is alright but could have just been a flat game. There is nothing immersive in Moss that you'd expect from playing a VR game.
Still a competent title and better than run of the mill shovelware.
The guy from the video disagrees, he says the experience is vastly better with VR, gives it some magical extra quality or something.
Yeah looking at the vid I'm sure you probably get a strong sense of "presence" (sense of being present in that virtual space watching those characters' antics as if they were real). Looks cool.
If no one else saw, you control the mouse via the controllers like a standard joystick, but you also control some parts of the environment using the controls as motion controls, like pulling a lever, pulling an ancient box etc...
Kind of a metroidvania(light?) with some immersive interactions.
They even made the plants swerve when moving your hands over them.
Story-wise you're treated as a type of "guide" that this mouse found you, which I thought was kinda wholesome and fits well.
