Two words:
FUCKING AWESOME SHIT. OK, that was three, but you deserve that!
A. Awesome anime-style animation
B. The prologue was in the style of FF7 - a great story that I was following, great to introduce the movie. I believe that some people found it uninteresting because it was so long, so you should have made it a little flashier and easier to read. I still liked it.
C. Too bad you had no voices. Well that matches my FF7 comparison =P
D. There were sounds as the game was loading. I like to load different movies at the same time, so I would prefer no sounds while the thing is loading.
E. I liked the music - FF7 style.
Since i like FF7 you get a 9! (because there were no voices)
I suggest you make music for each mood or to foreshadow some events and combine that with voices. I see many flash creations that have boring talk-talk-talk. Music enhances the voices' message/mood. You COULD get a perfect 10 with that!
