About the game
MUGI blends action and puzzle-solving around uncovering a mystery, and it first launched in May 2026 solely as a cartridge for the MSX2, only now making the leap to Steam. This PC edition folds in a newly arranged score, a high-score board that lets players type in their name, a tutorial for newcomers, and a built-in editor for designing and posting your own levels. The title is developed and published by 反動のゲームちゃんねる, with this Steam version out in 2026.
