The game follows a traditional Japanese adventure template. At every screen, a menu with verb commands appears. Commands differ from screen to screen, but usually include "Look", "Talk", and "Think". There is no movement of any kind in the game. It is usually required to go through all the commands and vast amounts of text and dialogue to advance the story.
