This is the ultimate scene creator
I do not know how this could be any better. You have a lot of different sonic zones and all of the music to go with them. I understand that you are not going to make a sonic scene creator and if you did, then it would be a heck of a lot of work. I gave you a 5 for violence only because it would depend on what the person does with the charecters, and I gave you a 10 for humor, because you can create some pretty random stuff with this. Overall, this is the best sonic scene creator I have seen on Newgrounds. So really good job.
P.S. There is only one problem, the Amy sprites on the Sonic CD and Knuckles Caotics scene will not move, but I don't count against you.
