Mischief Makers

Mischief Makers, known in Japan as Yuke Yuke!! Trouble Makers (ゆけゆけ！！トラブルメーカーズ ,lit. Go Go!! Trouble Makers), is a side-scrolling 2D platform/puzzle video game developed by Treasure, and published by Enix in Japan and by Nintendo in America and Europe for the Nintendo 64. It was released in 1997 as one of the first 2D side-scrollers on the Nintendo 64. The game's protagonist is the Ultra-Intergalactic-Cybot G Marina Liteyears (generally referred to as just Marina) who is a robotic maid of the absent-minded Professor Theo.

Professor Theo, a self-proclaimed "genius in robotics," is the creator of the game's main character, his robotic maid Marina Liteyears. He is kidnapped by the Empire upon orders from their evil emperor, Theo's estranged twin brother, who wishes to fill the world with hate and despair. Upon finding out about Theo's abduction, Marina sets out to rescue him.

She proceeds to travel through over 50 levels on Planet Clancer to find her creator. Every person, animal, and inanimate object on the planet (including the planet itself) has an identical "face," seemingly belonging to a species called "Clancer." Along the way Marina attempts to rescue the professor, but she is repeatedly impeded by agents of the Empire, whom she must defeat to accomplish her mission.
