Your goal is to make all elements, including with the impossible elements! You don't need EXTRA elements, there is no use for EXTRA elements, it really Do not touch Dioxigen to if you like it. The game is done. Play! DON'T READ OTHERWISE YOU'LL KNOW HOW THE GAME WORKS! Reason why Yttrium is in the Space Zone Sprite because, Yttrium is used for alloys... I added extra elements so that it will be more fun.
Has not really all the elements. Credit to everyone!
