Now press 'D' to cycle though the available weapons. Press 'C' to cycle though the levels. When entering a level always position your ship at the top left of the screen. On the second level repeat the above process and type "STONKER" again. You can now fly through walls and if you press 'F' you can hover over the switches and collect them from the air.
