No Case Should Remain Unsolved

Twelve years after Senior Inspector Jeon Gyeong's retirement, she is visited by a young police officer: a woman who pleads with her to reexamine Seowon's case. But with each uncovered memory, only one thing becomes clear: everyone in Seowon's vicinity was lying.

About this gameFull description from Steam
"I remember how surprised I was when I first saw this case. Everyone involved was lying, for one reason or another." #No_Case_Should_Remain_Unsolved is a detective game where players uncover and piece together memory fragments to solve a long-forgotten case. Follow former police detective Jeon Gyeong as she acquires clues and testimony relating to the case of a missing girl. #No_Case_Should_Remain_Unsolved February 5, 2012. A little girl named Seowon is reported missing from a playground. Police launch an investigation and question witnesses and suspects, but Seowon's case is never solved. Twelve years after Senior Inspector Jeon Gyeong's retirement, she is visited by a young police officer: a woman who pleads with her to reexamine Seowon's case. But with each uncovered memory, only one thing becomes clear: everyone in Seowon's vicinity was lying. Features Experience an imaginative reasoning system where players connect memories like pieces of a jigsaw puzzle. Uncover passcodes, keys, 54 conversations, and two hidden truths. Over the course of a 2-3 hour playthrough, players will learn why Seowon's disappearance is the only case Jeon Gyeong has left unsolved. Also featuring an original soundtrack by Seongyi Yi, composer of Legal Dungeon and The Wake!
