Parodius is a humorous shoot 'em up game for the Game Boy, a spin-off of the Konami's Parodius series. The game features quirky graphics, humorous elements, and intense action gameplay.  The Game Boy adaptation probably simplified the original arcade version's gameplay and visual elements to suit the handheld platform, but it likely retained the core elements of shooting down enemy planes and collecting power-ups.
