To be honest, is very good.
I already now how to create buttons and all that stuff, but I stop by to revise your tutorial. After a deep analysis I have to say that is very accurate and simple to follow. Each part has examples on the main program screen(which is very clear to see what is going on) and is very easy to remember by just doing the buttons while seen the tutorial screen. Nice work, keep it up, for all newbies this is kind of confusing but with some days of implementing the actual buttons into a flash work everything will flow easily. Practice guys! Well, keep doing more of this tutorials for the NG newbies!!!! See ya!
