Could be better...
Overall I was a little underwhelmed by this Flash, I was expecting good things after reading the blurb.
Concept was very good...in the blurb. Unfortunately absolutely none of that came through in your storytelling during the movie itself. The closest thing there was to a plot outline was the random collection of characters in the same place, but without any reason given, it just made things seem all over the place. Script was...well, it didn't have a whole lot to do with anything. You'll have to improve your storytelling for future episodes, you can't rely on the blurb to do all the talking.
Art and animation is a tough one to decide about. I'm a sprite agnostic, but you clearly did plenty of work with what you had available.... Full marks for effort, but it was a little uncomfortable on the eye at times.
Sound was fine, no problems there. Music was well chosen, and no real technical issues with the audio.
All in all - you've got a good idea, start doing it justice.
