The article mentions a trick whereby the other player clicked their "Camera move" stick instead of their "Character move" stick in order to fool the other play who could here the click the control pad made. This strongly indicates that the players are on different screens (close together in the scenario but I imagine usually it would be played over the net) I agree that it sounds like it would be very hard to make this into a playable game. But if they manage that it could be really good.
