Only good thing is the music
And it wasn't even done by you... Incredibly jerky and please for the love of god use the streaming since it's actually painful to my ears having Frozen and Memories play through my headset a billion and a half times.
I couldn't follow any of what was going on with the story. Only certain parts here and there seemed to be animated, while elsewhere the characters just flip around. Overall, it just looks jerky.
It looks okay for blocking out the general action, but as it is, it just looks like you posted an incomplete work. There's not enough animation to keep the story flowing.
And stop the music at the end, please. The music loops back onto itself every time the animation loops. Right now, I'm listening to maybe 5 or 6 overlapping, out-of-sync copies of the music.
Its called "Tweening"
Google it, then use it. Also, Get your music to stop playing when it loops back. Set the option to streaming.
