It's...my god. It's wonderful. Incredibly wonderful. Almost indescribably wonderful. I was very impressed with the story as a whole, and how you made the little Shadow Heartless (who are, indeniably, the cutest bad-guys in that game by far) creepy beyond belief. Your Yuffie is also a great and wonderful thing - I LIKE her, when I wasn't the biggest fan of the character in Final Fantasy VII.
I look forward to your next updates with great anticipation. Rock onwards!
