I liked your prealoader ^^.
Well, the main menu looks quite nice, but you should choose a darker colour for the text, as it is quite hard to read. It's a good thing that the text turns black when one hovers the mouse over it.
It's nice that you provided us with a mute button, as it can be quite annoying to listen to the same songs over and over again. But why did the first song always starts again whenever I click the "next" button, even though I turned it off the previous frame? You should try to fix that.
The layout of this tutorial is quite good. However, it would be a good idea if you'd name the single "steps", so that it will be easier to go to the chapter one was looking for. "Step 1, Step2, etc." aren't that helpful when looking for information about a specific theme.
What hurts this tutorial the most is the small text. It's really hard to read in combination with the font you chose. So either add an easier to read font or make the text bigger.
