Overall amazing! The interpretation of the theme was very creative and the execution really well done. I was a little bit stuck at the beginning, since I didn't understand that the atoms needed to have every orbital filled with electrons of the same spin before they could receive ones with the opposite one, but I thankfully remembered my chemistry lesson on this xd -- the "Common Confusions?" segment on the itch.io page was also very helpful in figuring out stuff. I'd love to play more of this if you decide on adding extra content!
