You are sitting behind a desk holding the control buttons on your keyboard. The game will try to scare you into letting go.
So all you have to do to win is...."Don't let Go no matter what!".
The title of Don't Let Go says it all: Hold down the Control keys on your keyboard and don't let go, no matter what happens. (Hint: Distracting things happen.) It's a little goofy, but this is a great way to ease someone into virtual reality—you're still sitting down in a chair holding onto a keyboard, and there's no real need for fast movements.
