Blast Wave has a great tutorial that you should go through first in order to get the feel and the controls of the game. You start in a place called the Happy Space, where green chaps live. There have been some tears in the space, and very angry red chaps have come out of these tears. Hold down the mouse button to gather power, and then release the mouse button to blast the green chaps away. You're trying to use them to hit the red chaps back in the hole, kind of like pool. Don't put the green chaps into the hole though, or you lose them forever! Each level presents new challenges. Can you save the Happy Place from destruction?
