Holy shit!
There's nothing more to add about the graphics or style...they're completely flawless, as is the animation.
The spooky music totally made this flash. It would be enough with the amazing style already, but the music took it to a whole new and creepy level. The voicework was also great, although I didn't think Melony's voice really fit. However, it's the beginning of the series and since we know nothing about her character anyway, I guess this is no place to judge (yet).
And to top it all off...this only took you eleven days?!? Just amazing. One of the few times my jaw has dropped while watching a flash. Can't wait for the rest of the series!
