Deadline

Deadline is a traditional detective mystery adpated to adventure game format: a mansion, a murder, and the usual suspects. It differs from the episodic paradigm of treasuer hund, bewildering maze, and tough monsters introduced by Adventure and instead confines the action to a limited space . . . with almost no hidden rooms, no mazes, less then fifteen, all human, characters (if human is the right word), and an intratextual time span of twelve hours.
