Who knew a game based on pixels could be so difficult and so much fun? You play the teal group of pixels located at the bottom of the screen. Starting at the top of the screen, a wave of invaders comes at you! They move from left to right on the screen, constantly moving down the rows towards you. You have to shoot them all and completely clear them before they reach you, or you die! Getting touched by the enemy or getting hit by one of their shots kills you. To move, just move your mouse around the screen. Click to shoot. It couldn't be easier!
