I had that game. It's 2-player hotseat, right? Even though the attract mode shows 2 computer players taking potshots at each other, I never found the option to play 1 player vs. an A.I. opponent.
One thing that impressed me was the way the hills were drawn and dotted with trees, it gives the impression that they are procedurally generated. It looks like this game was originally released for the Atari 2600, and also ported to the Commodore 64 and VIC-20. There is also a remake being developed for Pygame.
