Otoshi Deka - Keiji-san, Watashi ga Yarimashita — About this game
Otoshi Deka places you in the interrogation room of a police drama. Gather information and supporting evidence, then question a suspect and look for lies or contradictions in the account. Clearing a scenario requires drawing out a confession within the detention period, so the order of your inquiries and the strength of your evidence matter. Begin by understanding the case and the suspect's initial statement before pressing a particular point. A forceful approach and a colder response are different tools in the psychological exchange; the purpose is to connect what the suspect says with what you can substantiate. Read each new reaction before choosing another line of questioning.
