If you download the source - open the editor and go to the tetris world class - remove the part where it adds the Overlay Object and the MiddleLayer Object in the prepare method, you will see the underlying game.

Thanks! That is a good idea. I want to add more to this game. I was originally going to give limited fuel to the helicopter so you would have to shoot the fuel containers. I am drawing up a second level. Maybe I can add various play modes, let this mode be easy mode and harder modes make you pick up fuel and bombs.
