I really like how you got the characterization across so effectively in the first few moments.
Being of great power, but lacking control despite their best intent, paired with a person who can accept the limitations of such power, but still be reasonable emotional, leads well into them being a fusion dynamic.
Also the pitch black eyes are awesome, and you where able to put an reasonable ending as you and the characters where self aware enough to know that going further was not 100% necessary, and while I would have like to see more of your dynamic animation, I really enjoyed this.
Thank you for making it.
