ok: 
F1 - F5 control the scroll speed
F11 stops scrolling

F7 decreases gamma
F8 increases gamma
F6 restores gamma to normal

Arrow keys scroll the view

ESC exits

don't know if gamma control will work, :( sorry, it works for me,
besides its just a test.

you'll notice a scrolling backround, tiled.
there are 6 differnt tiles, two of them are animated and difference between them
is the speed of frames.

over the background there are ugly missiles standing, (I made them myself, which says too much).

enjoy, next I'll add something to walk between the missiles.
