Here's a few things I found wrong with it.
It is a good flash but it could be so much better!
The speech bubbles... I know you are looking for voice actors (which isn't bad) but for now, I'd rather have a button you can click whenever I am done reading the bubbles.
At times, the text goes by too fast, and I can't read the entire thing.
The screen is too small. Flash is a "lined" program rather than a pixel program, so you can set the screen size anything you want without it getting fuzzy. It also makes it harder to read the text.
I don't mind the detailed backgrounds, but you don't need too much detail when it comes to backgrounds, or at least that's what I think because no one is going to notice.
The movement in the characters we ok, but it wasn't animated too well :p
Last thing I noticed, the sound wasn't set on stream! That's buggy XP
