Note of Janus

Note of Janus is a single-player mystery adventure in which you play an architect summoned to Marquis Ethan’s mansion to plan an extension. You meet the marquis and his family, inspect the mansion and investigate strange events leading up to a terrible incident.

Investigate the mansion

You arrive at 8 a.m. and can act freely in the mansion until the incident takes place at 8 p.m. You can examine rooms and hallways or move between locations; each action advances time. At noon and 8 p.m., you go to the restaurant for a meal. The mansion’s residents will not approach you while you remain in a space, but entering a space where someone is present may let you overhear a conversation or speak with them.

You have limited time to gather information, and may not solve the incident before the day ends. If you fail to get to the bottom of it, time returns to 8 a.m. You must investigate the time loop and uncover the truth behind the events in the mansion.

Keep track of clues

You carry a pocket watch that lets you check the current time, and a notebook that automatically records meaningful discoveries and conversations. The notebook’s contents remain unchanged when time loops back to morning, helping you keep track of information across repeated investigations.
