Control the white ball by using the arrow keys on your keyboard. You will need to stay on top of the blue box - but watch out for the grey balls which will knock you all about the screen. Keep at it as long as you can, dodging the erratic movements of the grey balls, and notice your score going up inside of the blue square the whole time. As long as you can keep the ball within the confines of the blue square, this number will keep on increasing... but the second that you are knocked out from the square, it's game over and you'll have to start things all over. See how long you can last and how high of a score you can pull off in this fun and challenging game!
