Where to begin?
I really liked your animation. There are some problems though.
First off, (as others have said,) the voices, and the way you showed who was speaking sucked. Really bad. Consult some voice actors or something.
Second, you could develop the plot more.
Third, and most important, don't use the publish feature on flash to export your animation. Use the EXPORT feature. (File>Export>Export Movie) It'll come up with a list of things to do, pretty basic though, you can just leave the settings on it alone and export it like that.
Fourth, I'm looking forward to the next installment.
