Liquid Puzzle

Another water-sorting puzzle, and it sticks close to the format: tip liquid from one glass into another and try to consolidate each color into its own container. What makes these games live or die is the undo button, and here you get one, which takes some of the sting out of a careless pour three moves back. Early levels use two or three colors; later ones pile on enough glasses that you'll want to plan two moves ahead instead of one.
