hmm
Inherent despise of all things anime aside, this was too short. It was akin to reading the back insert of a book... a one paragraph introduction before you read the story. I don't care how good it looks if there's nothing palpable learned from watching it.
1. There's a bad guy.
2. Ken's protecting the good girl in some pendant.
That's it. Before you go making a flash, it would be wise to make a list of all critical story points beforehand and see if it is indeed enough to make something meaningful.
I say this not to be overly critical, but in honest concern that you add more depth and thought to things other than the flash's visuals and audio. Great story can mask any quality of production values, but high production values can not mask a poor story.
So if you continue this series, which I am assuming you will, please take this to heart and in future releases concentrate a bit more on points to further the plot. I know you can.
