All-star!
I think this may in fact set the record for the most voices ever used in a flash cartoon here! I kept thinking again of "Neon Genesis Evangelion" especially when you mentioned the angel or something like that. The animation was not great, but it was fairly satisfying. It is a bit hard to get into the story but what matters is that you put so much emotion into these characters and their facial features. Everyone really gave depth to the character he or she was voicing. I am surprised this series is not more popular.
