Build different types of objects with different elements to help you on your journey. You start at the smallest size all the way up to celestial bodies. E selects an atom and you can place it on the board. Note: make sure it's only touching one box so you don't make duplicates. BTW when crafting, if you don't know how to craft or what to craft, hit the craft button or look up on Wikipedia.
