Did you say Rocket-Car-Helicopter-Submarine?
The Red Switch was the first game I created for the Experimental Gameplay Project, in August 2009 for the "Bare Minimum" theme. It consists of a Rocket-Car-Helicopter-Submarine, which you pilot around various obstacles using a single button. Or... you can use multiple buttons, but they all do the same thing.
