Yep, exactly as you say. Totally game over, you enter your initials - then it grants the extra ball as an award and game resumes at the score you were just awarded for! Pretty neat actually! You know, you get to the end of one of those great games, get to add your initials, well that's a pretty good reward - but this game goes one further and lets you have another ball to really reward you. I almost want to clear the high scores to get it more often (but that 1.8 billion game deserves to be left, bugger!)
