Brilliance! Absolute brilliance!
I loved every second of this! A terrific video with an excellent score, and animation as beautiful as the world it's in! These are the kind of flashes I adore. No offense, but this beats your XIN series in every imaginable way. I can't wait for part two. Everything about it screams originality, imagination, and overall innocence clashing with curiousity of the unknown. Keep the scoring as brilliant as it is as well, the music is a huge part of why it's so great.
Easily 5/5.
