Not quite sure what's going on #atari2600 #yarsrevenge
@Twig You shot the Qotile! Congratulations! (Now on to the next, harder one.)

@EclecticLee

Not quite sure how I did that. But I'll play it again and learn what's going on

@Twig The manual is available at AtariAge.com, but basically you either reduced the shield to where you could shoot it with your cannon (obtained by eating some shield and appears on the left) or you shot the fire ball it shot at you with your cannon. Be careful not to shoot yourself with your cannon.

@EclecticLee Thanks! I did look at a video on YT, but I guess a manual would do a better job.
@Twig It probably depends on whether the video explained game play as it went or not. It's not really a complicated game, but neither is it completely intuitive.
