Another Code: Two Memories (known as Trace Memory in North America) was developed by Cing and published by Nintendo in 2005, very early in the console's life. It follows Ashley Robbins, a teenager who arrives on an island to unravel the past of her missing father, solving puzzles that use the microphone, the touch screen, and even the console's closing hinge as part of the storytelling.
It's one of the most cited examples of how DS integrated its specific hardware — two screens, stylus, microphone — in service of telling a story, and it remains an essential reference for anyone wanting to see the machine's early narrative potential.
