Little Alchemy

At the beginning, there was only water, fire, air, and earth. As time went on, these basic elements merged together, and created new, totally unique elements that are nowadays considered as common ones. The more and more years have passed, the better inventions were, and the more complicated things began to appear. But just go back in time, and start from scratch. Merge foundation elements together, and see what comes up from that. Reveal new elements by merging newly found combinations, and expand your area of inventing. There is 560 elements to be discovered. Have fun.
