You’ve just obliterated the last seven or eight zombies. It was a narrow escape and you’re flushed with satisfaction. But you didn’t see that horrendous creep, weaping sores and oozing pus, because he was hidden behind the dustbin in the shadow of a bombed out building. You get slimed, you’re dead. Or worse than dead. So you touch the “play again” bar at the bottom of the screen. Now you start further ahead than last time. You know you’re going to meet the slime-master again. Soon. Be prepared.
Or you’ve crossed the desert and scaled the abandoned fortress, nearly to the top, moving along pathways that require hair-trigger adjustments with your joy-stick. But the wind is getting stronger by the second. It keeps pushing you back along the path, dangerously close to the edge. You make a daring dash between gusts. But you miscalculated, and the force of the wind blows you right off the edge. Down you plummet, to a plateau you crossed minutes ago. Now you have to make that climb again. But do it better. Get it right.
