Color Pixel Flow

Color Pixel Flow is a puzzle game with a strange and very likeable premise: you send pigs down a conveyor and they rain balls onto the pixel cubes that match their colour. Each pig carries a number that tells you how many hits it has left. Spend one badly and it walks off the stage, spend one well and it heads to a waiting slot ready to go again. Working out the order to deploy them in is the whole game. Free in your browser.
