You control the silver ball. The tiles will fall really quickly, and quicker as you progress. To avoid the tiles, press one of the following keys: [left arrow] for left position [down arrow] for center position [right arrow] for right position Comment your high score (it will probably be low) Mine is 6.
The action will start one second (according to the timer) after the space key is pressed. This is not a bug, this prevents the tiles from jittering all over the screen, making you lose.
