After being a Sonic fan for a while, I have been disillusioned about nostalgia. This game is not really creative, and the gravity is tedious. I know that you may have been trying to make a "Nintendo hard" (just try playing Scrap Brain) game, but the gravity screws up the gameplay quite a bit.
I didn't try the music because I just don't feel the need to listen to it, but anyways, if you take away the veil of nostalgia you get a poor game. I am sorry, but that is how I feel this game should be rated.
