Abunai Tengu Densetsu is an adventure game with menu-based navigation and input. Most screens offer a fairly long list of verb commands, some of which must be combined with objects or persons selected from a sub-menu in order to interact with the environment. The game allows the player to visit many different rooms and other locations in any order; however, certain events must be triggered in order to advance, sometimes by repeatedly selecting commands. Certain situations require the player to find items and use them in a different location.
