Oooh, this is an interesting prologue! I like the mystery of the number! And that mystery character that busts in at the end!! And don't worry, you're not the only one who is revamping their old content! (coughcoughCorvid Kid)
I felt that the only thing that was a bit lacking was the design of the main character Kare. I found that in some scenes I mistook him for a background character. Unless that is intentional, then don't mind me.
