its good but i should make this note...
I believe that the creator in itself is a good idea BUT it needs a way to turn the sprites around so that sonic can face shadow and/or dr.robotnic face right rather then always left so you can use the tails being catpured sprite with robotnic flying away. also i believe the music should able to be turned off. One more thing is the sprites that flicker (bubble shield, Explotions, eta) have a tendency to not click...the shield is the one i have the most problems with...that is not a big problem tho. But i believe the sprites over all should have the option to face the other way. if there is a way to manage this then please, Enlighten me... (sorry for my horrable spelling if any mistakes are found in this review)
Your friend, Violet! ^_^
ps:Sonic is awesome! :3
