could have been way better..
The buttons were too minimal, i think you should have made the buttons with the "on" (when the mouse is on the button) and "klick" (when the mouse is klicked on the button) frames on it.
it would also be better if you'd explained what the actionscript on the buttons mean, i know that sounds pretty lame but if you want to teach people how to make them, i think they shoud also understand how it works.
And another thing about the actionscript, the "gotoandplay(2)". not that it's wrong, but it doesn't have to be just frame 2. I think you should have explained that you can choose whatever frame you want (and whatever scene you want) and not only frame two.
And the whole thing simply looked too boring. you've could at least added a background.
And the finishing touch would be if you'd show some nice flashy buttons instead of just an black and white image with some actionscript on it.
