Were Wheatley to get his own game, we’d pick up right where we left him, floating around the moon. After learning the error of his ways, Wheatley teams up with his fellow floating spheres and tries to find a way home, propelling himself in zero gravity through a series of clever puzzles. Having the bumbling AI complete physics-based conundrums sounds like a fittingly scientific approach for a Portal spin-off.
