As the game starts you move the blue joystick to control the blue plane on the screen as it moves right, and you use the green button on the machine to blast at the enemies coming at the blue plane, which were purple hairbrushes, that were pointing white lines at your direction. As soon as you see them, your airplane blasts them.
With every enemy you hit, your high score increases from 0, to 10 points per point. You manage to shoot 15 hairbrushes giving you 1500 points on your high score, then a text box opens in front of you. A sentence appears on the box, asking this question. "What Style Do You Want Your Hair To Be?" Below that sentence were the choices of hairstyles for you select, and then one more sentence pops up below the choices saying "Use the Yellow Button to select your choice of fashion."
So the Blue Button starts, and pauses the game, the Green Button was for shooting the enemies, and the Yellow Button was for selecting items during the game. While you wonder what the Red Button is for, you decide to select a hairstyle.
