There is my review:
This is not that we expected but was realy nice.
But some animations were completely out of synth (like Amy moments).
Music selection was amazing.
Yet i think you was trying to make it into Dragon Ball Like series. Shadow is completely was this time like Vegeta in new movie, while other fighting he is standing and does nothing, then later goes into attack with all he got.
P.S. I liked it in sprite style but still great one. Good luck with next one.
