I really like this game it is very fun you can unlock different kinds of characters in this game like Sonic Amy Knuckles Tails Shadow sticks Rouge and the new character that was added to this game Vector the crocodile even though I have been stuck on a level this app is very fun to use that is why I want to give this app five-stars because I really like it people think this app is not cool but is it is cool some people give it one star and another person gave it three stars because she liked it.
