No Case Should Remain unsolved is a fantastic adventure game that runs at about 3~ hours but never understays its welcome. Abstract, narrative-based indie games have had their time in the sun in the past decade or so but No Case Should Remain Unsolved nonetheless manages to keep things fresh with how it intuitively dispenses its narrative and intertwines it with the gameplay. The protagonist is essentially piecing together memories of a cold case about a child kidnapping that appear in the form of instant messages. The entire game takes place within this screen, more or less, but there's a very satisfying quality of working out the "how" and piecing together related fragments of the messages, while drawing inferences to guide you to the next piece of information that needs to be looked at. It's really something you have to try for yourself but it's immensely enjoyable and hits the sweet spot of "challenging, yet fair".

Hard to go to deep into the writing without spoiling anything (which I don't want to do), but it's excellent and the story wraps up very nicely.
