  32 Still To do:
  33  - Make original speed and further increases in speed depend more on screen size
  34  - attempt to make the tunnels get narrower as the game goes on
  35  - make the chopper look better, maybe a picture, and scale according
  36    to screen size
  37  - use textures for the color screens for background and terrain,
  38    eg stars on background
  39  - allow choice of different levels [later: different screen themes]
  40  - better high score handling, improved screen etc.
