We were proceeding through a maze and facing a series of challenges, in which we had to give up various things. For example, two of us had to give up a sense, so I gave up my sense of fashion. Things like that. We reached a point where we each had to give up something important to us, so I posited that gravity, being one of the basic needs of life, was important to all of us, and we then surrendered it. And spent the rest of the game floating.
