Click the Earth to earn money, and then, once you have enough, click the other buttons to get more money per click/second. The numbers to the left of the dollar signs are how much it costs, and the ones to the right of the plus signs are how much you earn every click/second. The right side is per click shop, left is per second shop.
Credits to @magos23 for the original game, "Clicker game Beta V.10", and for asking me to add a CPS/Click Per Second shop (I suggested the idea). Credits to myself, aspentreeabsenttree, for the CPS shop (still working on it!).
