Good voice actors.
Like I said. However, there are some obvious problems. For one, the artwork should match the quality or at least be stylized enough that it works with the voice-acting. Secondly, a lot of your voice clips changed volumes when a character said different phrases. It was obvious that the clips were recorded under different settings. I'm not sure how you would revise this, but it is something to look into. Good Luck with future projects!
Unfortunately there is no set standard on the recording volume, since some will record their lines loudly, which give me better flexibility on how loud I want it; and some will record their lines quietly, which is guaranteed to have no disruptive cuts and pop caused by being too loud. This is one of the limits of an amateur online production.
So in the end, I'll over or under compensate the reduction of the louder clips to match the quieter clips. Flash can lower the volume, but it can't amplify it. I got SoundBooth (it's enough for me), so hopefully I figure things out from there.
The voice acting was very anime-esque. I thought it worked will with the animation style. The text onscreen did not always follow what was being said in the voice over.
