No Case Should Remain Unsolved is a mystery-themed video game. Developed by South Korean indie developer Somi. The story follows a retired Senior Inspector, Jean Gyeong, who is reexamining the disappearance of a young girl named Seowan. Gyeong can only relive her memories of interviewing suspects, such as Seowan's parents and a man who confesses to the kidnapping. The gameplay predominantly has players reading through various testimonies of people involved with the girl and re-arranging them in sequence and by character. To uncover new testimonies, the player selects words that stimulate memories within the existing testimonies.
