Basic info:

Money/resources is in the top left, and the shop is on the left (prices are the upper left number on the atoms). You start with 1 Hydrogen atom at the top which you can click to place in a valid area. When you obtain more atoms, you can either place them or click on an existing atom to create a compound if one is available. Atoms with available compounds will be highlighted. There are infinite levels, but you are limited to 10 atoms/compounds on the field at a time (atoms can be deleted with right click), so try to get a collection of strong compounds! 

This game was made in a couple weeks and is just in a prototype state. I am unsure if I will have time to revisit it, but I do have a lot of ideas for what to expand on. At the moment, the Lewis structure system is not accurate.
