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