Short. Pointless.
Before you submit somthing, you need to ask yourself "Does this submission serve a point? Does it show a story, how to do somthing, and is it long enough?" This submission dosen't fit that cateigory and because of that it isn't enjoyable. If anything the song is the best part of the submission. Maybe next time add some sort of background, and smoother animations. Maybe different types of characters or somthing. All in all a below average submission. I personally would not vote this in Newgrounds.
