I'd recommend adding an option to exit the game through the Escape key, with a confirmation prompt; and perhaps an Exit option to the main menu. Other than that, it's a pretty interesting game.
Well, I ended up emptying my bladder into my bed, I was under the impression it was a simple walking simulator. I do have a recommendation, instead of immediately exiting the game when the ESCAPE key is pressed, it would be better to display a prompt.
This game is pretty interesting. It can actually be played without a VR headset using the mouse and keyboard controls, although the environment lacks collision.
