wow
music was bad. Animation though ok was crazy. everytime sonic jumped it looked like he was drunk in the air he moved in random zig zags as he went by. it was tiny so it was hard to see. Ima give you a 0 but heres some good points to help you.
Replace the music with any battle or boss battle BGM easy to get easy to use.
Animation curved lines make jumpes look better you had the rise and fall nice next time curve the jump it takes some practice to get it right i understand that trust me i do.
Its 8/16 bit sprites man blow it up its ok to see the choppy lines we expect that on those sprites.
Im looking forward to your sequal in fact im gonna add you to my favorites just so i can watch how you do. You got talent lets see it.
