Update 12-31-2014: TO ANYONE WHO WANTS TO PLAY IT : IT ONLY WORKS UNTIL YOU SEE THE BLACKISH BACKGROUND. YOU CANNOT CONTROL SONIC OR SHADOW YET.
Used sprites from online and backdrops from online (2 out of the 3 backdrops) and 1 backdrop I made myself. The code was completely created by me. If you want to remix this, feel free to do so.
