Gameplay

Maomao combines observations, interviews and medical knowledge to solve the Five Mysteries and Five Curses. At the locations, she searches for clues, collects ingredients and makes medicines. In her notebook, she organizes statements and evidence that she must present with her conclusions. Wrong answers can reduce the trust of the person she questions.

Some sections also let Jinshi and Maomao be playable as a cat. Thanks to his position at court, Jinshi gets statements that are not directly accessible to Maomao. As a cat, she can reach higher spots and eavesdrop on conversations. While mixing medicine, other characters can temporarily be controlled. Alongside the investigations, missions and medicine deliveries open additional stories with other characters.
