This was one of my favorite games for my Atari. The plot involves the fly-like Yar picks his way through the wall to get to the base of the Qotile. Then when the hole is big enough you can fire you cannon. The game was created by the great Howard Scott Warshaw and was a great seller at the time. I think everyone I knew had a copy, but while others perferred the port of pac-man or a pedestrian game of Frogs and Flies, I was clearing level after level after level with no end in sight.
This commercial still sticks in my head. When I found it online, I could still sing all the lines. Watch out Yar….
