You give tutorials a bad name.
The Zelda music wasn't necessary. I have no idea why you need music in a tutorial... let alone Zelda soundtracks.
The graphics were too mixed up, you had a RuneScape character follow the mouse, which just added to the lagginess, while Mario stood around in mid air with a fancy pop-up text bubble in the middle of the screen. I noticed the next button in the corner, but others might not notice it, because it isn't very obvious that you click it. The background wasn't really necessary either.
The blur effect you included didn't really look good newayz.
