Jihai Shonen Met Mag

Released in Japan on July 3, 1987, Jikai Shounen Met Mag (Magnetic Boy: Met Mag) is an innovative physics-based puzzle game developed by Thinking Rabbit and published by Square under the DOG (Disk Original Group) label for the Famicom Disk System. Across 100 challenging stages, players must collect all orbs to open an exit, navigating environments by manipulating the protagonist's magnetic polarity. 

By switching between red and blue polarities, players interact with magnetic floor tiles and blocks to either repel themselves for high jumps or attract themselves to surfaces. The game notably allows players to choose between two protagonists—the boy Met Mag or the girl Matt Meg—whose starting polarities differ, adding a layer of strategic planning to each stage's solution.
