You only get one chance at the 50th level. If you fail to finish it, you get
the Game Over screen followed by a chance to enter your high score. If
you do finish it, you get the following screen: Against a black background,
three "CONGRATULATIONS" stacked one atop the other (each one flashing
in different colors like a neon sign), exploding fireworks coming from the
bottom of the screen, and a two-note theme repeating over and over.
Hitting start brings the high-score screen, after which the game resets.
