Play Twin Online

Twin was a Game Boy puzzle game released in 1990 by developer/publisher Atelier Double. It arrived during a period when the handheld was becoming a serious platform for thoughtful, mechanically-driven experiences, not just action or arcade ports. The game didn't aim for spectacle; it focused on a single, clever idea executed with precision.

You control two characters simultaneously, one on the left side of the screen and one on the right, with every input mirrored. Your goal is to guide both to their respective exits on each stage. The core mechanics involve navigating maze-like rooms, pushing blocks to clear paths or create bridges, and avoiding hazards that kill your characters if they touch them. The difficulty is steep and cerebral, demanding you plan several moves ahead to account for the mirrored movements. Solving a particularly stubborn stage provides a genuine sense of intellectual accomplishment.
