Many Many Glitches

Overall the story was pretty good but i would have given you a higher score if it weren't for some glitches! Everytime cpeople leave the screen they stay att he side of the screen in the black area.So they just stay there like walking idiots. An in one scene where sonic or pierre attacks yoshi he stays spinning in the side while at the same time he fightin someone else! All im saying is to delete the sprites when they go off the scene!
