Pretty cool...
I will admit you have me liking this in general. A couple of personal buggy things. The audio loops should loop seamlessly, most likely you have imported an mp3, try and get it into a WAV format and import the wav, it sometimes helps with the glitch. Also, there is a stutter before, I assume, the next batch of characters are let lose, you need to optimize your code there, message me if you want any help. Keep it up, ActionScripting is awesome.
