This game is super zen.
Excellent tutorial and great gameplay concept! The game looks amazing, and the ethereal music is just out of this world! Very impressive! Did you compose the music yourself?
A little comment on the gameplay: the only thing I didn't like was having hitboxes on the avatar-tail, it felt very unforgiving dying from a tail-hit, because the tail moves around relative to the player rotation. I would prefer only dying when hit on the "main circle", if that makes sense :)
