Breaking blocks can be difficult unless you have your little Goo's to do it for you. At first there is only one Goo and one block, but as the levels progress more Goo's will join forces and break blocks, but that just makes your job more difficult. There is a bar that moves from left to right and the objective is to left click every time the 'moving cursor' passes over the white line in the bar. The more accurate you are in hitting the middle of that white line, the more points you will score. Go ahead and see how good your reflexes are and click your way to victory.
