I love the reactions! There was just a lot of text, but I appreciated the help buttons next to each of the tests. I liked the music. I think I'm just confused about how the mechanics worked- almost all of the rocks scratched, but they still sold for a lot? It was supposed to be the most reliable test, but then why did they all scratch? Maybe I just don't understand how it works, but it just seemed hard to judge based on the given information.
