It was actually a pretty complex handheld. Basically space invaders but it had some other gameplay functions besides move side to side and shoot. My dad loved it, so much so that he got pissed off and broke it. So I never really got a chance to play it. Later him and my mom bought snakes revenge on NES. They hated it, and refunded it for tetris. Then the real addiction started.
