Chronos Twin review at N+.

"N+ have been following the development of Chronos Twin on the DS for over a year. The game takes advantage of the handheld's two screens to create a unique time-travelling platform game that lets you control the action in the past and present simultaneously. We were given the opportunity to play Chronos Twin and get to grips with the game. Two screens, two times, one review."
