Great Site! I love it, simple and smooth. I think that you shouldn't lose the menu when you go to a secondary page (resources). Users like to find the nav menu in about the same place. You could always move it to the left a little or make in thinner but it should still be there so I can get to any page from anywhere on the site.
Love it since seeing your website it inspired me to do my original idea for the puzzle website seeing how you did the rollover picture buttons. Your website is fun awesome and simple dont think I would change anything.
