Yokai Buster: Ruka no Daibouken

De Sting Entertainment

Game developers Sting' were contracted by the publishing comglomerate Kadokawa Shoten for a tie-in game for their gaming magazine Marukatsu Super Famicom, which had recently just started pushing a new mascot named Ruka (with an accompanying mini manga in each issue) to try and help boost sales of the magazine. Rather than create a new game from scratch, Sting opted to re-brand the already existing "The Jetsons: Invasion of the Planet Pirates" game they had released the year before, which had not been released in Japan. The gameplay and level design between the two games is ultimately the same, though the story, sprites, and artwork were completely redone, as well as music.
