Man! Unbelievable! I wish I could. Not only make such games, but solve it. Stuck at level 17... ;)
My two cents for improving this game: If I have more than one action I want to click another atom while the electrons are still flying. And although the music is nice after a some time (and I spent a good amount) I wish another song would come up.
A question: I always struggle withwhen it comes to creating puzzles. How do you make levels? Thinking for hours? Using a clever algorithm? Or are you just one of those who just invent them? ;)
