Kaen Seibo is a Japanese-style adventure which relies largely on conversations and the choices you make during them. However, the game also contains elements of Western-style adventuring. There are items that must be found, picked up and used at appropriate moments. There are areas where you can move through a 3D-like environment, viewing it from first-person perspective. During the dialogues, you also have commands that are accessible through a menu. There are also segments with a time limit.
