Sanma no Meitantei — About this game
The player instructs the detective, Sanma, to solve the incident that occurred at the Yoshimoto family's party. The basics of an investigation are to call the people involved, ask them questions, investigate areas of interest in the room, show them the items they found, and elicit their testimonies. New information will increase the number of places you can go, and other people may appear in places you've already visited. Don't get distracted by the laughter of the conversation, and proceed by sorting out the relationships between the characters and their alibis. Actions such as tracking are also available. If you use the notepad you get along the way, you can remember the password for restarting.
