***** PLEASE DO NOT READ THIS UNTIL YOU HAVE TRIED THE PROGRAM *****


The game is remniscent of Snafu or Tron Light Cycles, if you are familiar
with those.  If not, the game consists of two 'cars', represented using
lo-res blocks, that the players drive around the screen.  Each car leaves
a trail behind it.  The game continues until one of the players crashes
into one of the trails or the walls of the screen.  The object is, of
course, to trap your opponent and stay alive longer.

If you don't have a second player, then you can also try to challenge
'yourself' by driving both cars and seeing how long you can stay alive.
There is a counter that keeps track of time at the bottom of the screen
for this purpose.
