A villain that's NOT Dr. Eggman?! Absurd!!
the only downside I can see is that the controls are a little annoying.
Another great thing about this game is the graphics! They look real and it looks like your in a book and in a desert! It's just all so visually appealing! Some minigames can be a little hard and frustrating at times, same with the challenges. The dialog is also fun and entertaining unlike most sonic games it is not trying to be witty it just is funny.
In conclusion sonic and the secret rings dose really hold secrets and surprises for those willing to play it.
