When you start playing there will be a green circle that will follow your mouse. Move the green circle over the blue circles that appear, a letter will show up. This letter should be A,S,D, or F, press the letter on the keyboard and move to the next circle. Once your power meter is full, press the space bar to go into hyper mode. When you are in hyper mode the green circle will turn red and then to kill a blue circle all you have to do is move the red circle over the blue circle. If you wait to long to kill a blue circle or you press the wrong letter, you will lose a life and your multiplier will go back to 1. You get an extra life once you get 200 points and then double that every time (200, 400, 800, 1600, ect)The game is less complicated then it sounds.
