Argh.
Forgot what I was going to say...
Oh yeah!
The music was really really really annoying. I couldn't read anything because it was so loud. It started out quiet, then... Argh!!
And the spelling was bad. DON'T EVER USE 'u' IN A TUTORIAL!!! And, on the very first one, I don't know if you did this on purpose as a joke or you just weren't paying attention, but it said, "Today we will be learning how to do will be learning how to add movie clips to buttons."
Another thing, at the main menu, you should put the name of the tutorial instead of just, "Tutorial 1."
It was informing, though, and that's what mainly matters. Just work on those factors and it'll be good.
