Play Zero One (J)(Mugs) Online

Zero One (J)(Mugs) is a Japan-only release for the Game Boy Advance, developed by Mugs. It arrived during a period when the GBA library was rich with experimental and puzzle-focused titles, offering a distinct take on tactical movement without the usual fanfare of bigger franchises.

You control a squad of geometric units on a grid-based battlefield, planning each step to navigate obstacles and outmaneuver opposing forces. The main objective is to guide your entire formation to the goal without losing units to missteps or enemy patterns. Signature mechanics include synchronized unit movement, where every command shifts your whole bloc at once, and environmental puzzles that require precise positioning to unlock paths or avoid hazards. The pacing is deliberate, almost puzzle-like, with failure often resulting in a sudden, cascading collapse of your carefully arranged team. It feels like conducting a fragile, digital machine where one wrong input undoes everything you've built.
