It's the classic story of boy meets girl meets puzzle platforming in Mattia Traverso's One and One Story, where your goal is to reunite two shadows separated by distance and hazardous terrain. Come into contact with spikes, or fall too far, and you'll die and have to restart the level. (Alternately, if you get stuck, just press [R] to reload a level.) Initially you'll use the [arrow] keys to move, and [Z] or [C] to swap between characters, but as stages progress and the intermittent level text narrates, this will change. The game is divided up into chapters, and each has its own set of rules as to how your shadows move and play off each other.
While One and One Story comes with a selection of bonus levels, the actual story campaign is fairly short, though not necessarily in a bad way. The game may look and feel all moody-broody like something Bruce Wayne would secretly code, but it's actually a fairly sweet and sentimental look at its core themes of love and relationships. If it were any longer than it is, it might feel like it was dragging its feet, especially since some stages towards the end can feel a little repetitive or finicky, combined with trying to judge distance between deadly and safe falls, and how close is too close to spikes. The puzzles, especially the ones in the bonus levels, are mostly well designed and challenging, but how well you respond to the game is probably tied in part to how much you identify with the narration. Gabriele Bonis brings a soft, beautiful art style to the experience, while the soundtrack by David Carney of DVGmusic is just top-notch. If what you want is a short, warm and fuzzy little puzzle game to make you go d'awwwww, One and One Story is worth a peek.
