Here is a review of the first game just to give you an idea of what it is

"Another Code: Two Memories is a fresh new Nintendo game that brings the classic gameplay of point-and-click PC adventures to its Nintendo DS portable system. Using the handheld's touch screen, players guide along fifteen-year-old Ashley, an orphan who sets off on a ten-hour journey to reunite with her long-lost father and uncover the truth behind her mother's murder. With talk of murder, suicide, and not a classic franchise character in sight, Another Code is obviously not your standard Nintendo adventure. In this case it's great news as the game's mature but tasteful story is one of its strongest merits."
