Why do you need info about this game? Its name says it all, doesn't it? :) Ok, your goal is to destroy those colored monsters while you try to avoid being hit by them. Use YOUR MOUSE to move and click to fire. Small filled circles are power-ups, try to collect them as they give you extra lives, upgrade your weapon or gives you special ammo. When firing hold the mouse at the top of the screen to use special ammo or at the bottom to save it for later. Have fun!
