Stop the circles from filling the screen and get the highest score possible. There are 3 power-ups: Reverse time, a power-up that converts 30 points into 10 seconds. Time Trade-off, a power-up that uses 15 seconds for 10 points. And finally, KILL ALL CIRCLES, a power-up that uses 60 points to kill ALL circles on the board.
Mildly interesting. Something might happen if you press 0 & 9 on the keyboard at the same time. ;)
