'This is a clone of an old Atari ST game.
'Move the tank in the mine field. A beep
'will indicate that there is a landmine
'in front of you or on either side. Avoid
'mines, collect bonus and try to find a
'hidden "extra life".
'Exit a level by hitting the red line
'on top of the minefield. Then you start
'over, with more mines.
