IGN writes: "The DS touch screen is a natural fit for graphic adventure games, and Unsolved Crimes is a competent offering that should give fans a small puzzle-solving fix. Visually, it's straight out of 1992 with its generic characters and ghetto animation. But the gameplay is solid, featuring a nice mix of exploration and evidence examination.
Unsolved Crimes comes by way of Japanese developer Now Production. These types of mystery games are pretty popular in Japan, and Now has experience both in this genre and with puzzle games like PQ: Practical Intelligence Quotient for the PSP. As is common with lower profile Japanese games, there are plenty of typos littering the text. The first couple cases rely on murder mystery clichés but the game eventually grows into its own adventure with some inventive and lengthy problems."
