Fair Enough...
For a first flash project it was pretty good.
It had a decent length, a few basic effects, and working play/replay buttons.
From what I've seen, people would be lucky enough to have a flash longer than 10 seconds, let alone functioning playback without an immediate loop.
...Of course those were just their First projects.
In the Information Box it says you used 'Final Countdown(DjEagle Remix)', although I heard nothing.
So I suppose figuring out how to add in sounds correctly would be your next step :S
At least from this point you can only improve so keep working on it and your skills will get better.
