Overall it's a fairly good implementation of a classic character who has had a surge in popularity lately. He's more or less accurate to Sonic Mania, translated to 3d, and works pretty well. He's not an easy character and I certainly haven't mastered him I think he has potential to be good if played well.
The art is merely serviceable, but as another review mentions, he has a very nice 3d model availible.
Finally, for those wondering, the asset is on a forum post, go to the Discussion tab and it will attached to the first post.
