Instead of posting our current score on the iPhone screen, like most developers do, he obscures it from view, only showing it to us after the game has ended. In addition to heightening our anticipation, it also allows us to focus our attentions on the game. Too bad the same developer also created one of the worst online leaderboards we've seen. Sure, Tunnel is free, but damn."
