Like its predecessor, De-Ja II is a Japanese-style adventure. The interface has been enhanced compared to the first game. Most of the commands are still done via the extensive verb menus and object sub-menus; once again, it is usually necessary to use those commands several times in order to gain new information and thus advance the story. However, in certain places, icon-based interface becomes available, with point-and-click interaction. The icons include traditional talking, touching, as well as less common commands such as hitting, and even an icon depicting a condom, for... err... scientific activities that are closer to anatomy than archeology.
