Before you play this I think you should know some things: - I changed the color palette so there will be a color palette glitch when ever you exit super mode.This can be fixed by going into a special or bonus stage and then exiting it. -The Majority of the sprites are finished,and the unfinished ones are less noticeable because of the changed color palette. -Knuckles color palette was changed too to make his shades of red look darker. -Any unaltered super sonic sprites were uneditable for me.
