I DID IT!!
I spent a lot of time on that last level but I was able to figure it out.
This was a lot of fun, and very polished. I enjoyed the gameplay mostly but I found that the levels with multiple actions were the least enjoyable. I liked the idea of triggering a single chain reaction with careful planning and those multi turn levels felt like they deviated from that.
Also, I found that if you quickly double click an atom with 2 electrons you can fire both off in a single turn
