Zenpen uses a command-based adventure format. The player moves between locations, selects actions such as examining the surroundings or speaking with people, and advances the time-travel scenario by choosing relevant responses and using items or information at the correct moments.

Progress is chapter-based and follows the first portion of the story. There are no action stages, combat system, or score-focused arcade modes; the main challenge is identifying which command or conversation advances the current scene. The Disk System format supplies the game’s storage and loading environment.

Read each line of dialogue carefully and revisit available locations when a scene does not advance. Adventure-game progress often depends on a newly revealed conversation detail rather than on a visible objective marker.

Keep track of items, names, and historical references before changing scenes. If a command appears ineffective, try it again after speaking to every available character or examining the nearby environment.
