I don't care so much about the all in one page, but having to roll over the image to see the text was too difficult. Took me a minute just to figure it out. Have the text below the image without having to roll over it. I also had trouble figuring out at the opening shot where to click. Took me forever to find the next button, I found it just in time. I almost left!
