White streaks are coming out of the bottom of the screen. When they touch the bottom, they sometimes bounce, but sometimes, they disappear. If one of them disappears when it hits the bottom, you lose. You can destroy them with the line that your mouse is drawing. But be careful—the mouse doesn't draw if you're moving too fast! As the game progresses, they appear more frequently. Your score is how many you destroyed. At the end of the game, the highscore appears.
