It could be interesting.
I don't agree with TwinsenDude. Sprites can be great, IMO.
I'm looking forward to seeing what you're going to do with the storyline, and how the characters are going to play out. Yes, it was a little slow, but it was a prelude, so I forgive you for that.
The only thing that I kinda had a problem with was your backgrounds. It looked like you took a screenshot of it and saved it as a .JPEG file. I use .BMP, .GIF, or .PNG so they don't get distorted. Also, they weren't in correct proportion to the characters . I could live with it, but... meh.
Well, good luck with your series. I'll keep an eye out for it. :P
