Okay, I couldn't understand anything that narrator was saying. Besides that the drawings were mostly pictures, and at the end, I couldn't read anything. I recommend you doing this:
Make animations- I know this will take a while, but great flash videos that everyone loves are not made in one week, it takes months.
Put buttons- This is very simple, just look at a button tutorial and add buttons. This should be no problem.
Make the narrator talk slower and clearly- Even though I talk and understand english, I couldn't understand what the narrator was saying (not to mention that it was Sam). Also add some music or sfx and fx.
That's all I recommend for now. Keep working and don't give up. I'm sure you will make a better flash video next time. :D
