UNFINISHED
Unfinished, that's the only word that define this game.
The story is interesting but not incredible. The model of characters is amazing, specially compare to the other sonic games that apears before this one.
But... the game can make you feel you're an stupid playing games, and trying to survive in one stage, loosing all your lifes only falling and falling, so is a nosense... and that's incredibly anoying because it could have been an amazing game, and it has finished being an "unfinished game.
At least, the silver stages are the best, only because you can walk slowly without running at top speed.
Poor sonic...
