Fun concept. I think it's nice that there's also a bit of an educational element to it (no pun intended). Though I did find sometimes the atoms would just bounce into each other and I'd win a level without even having to do anything. Good job!
There are quite a few bugs in my programming, and I understand they can be near game-breaking at times. Though I liked the idea of giving people a little chemistry lesson! I very much appreciate your kind words and feedback ^^
