I love quantum physics. I also love this game. I tried to form a pion, that didn't turn out so well ;)
Only a couple questions:
1. Where are the leptons?
2. What about the heavier quarks?
I love this game. It could use a few more things to make it even better, but it's still perfect for a 5/5 rating. One of the best quantum physics games on Kongregate.
