A perfect version of Sonic 2. Christian Whitehead is a beast and if I had any complaints it would be why are these versions of the game not on console yet?? Also people complaining about ads and whatever need to spend the 2 dollars it takes to remove them. Not only will you get a better experience but you will also be supporting the devs. If you rated this game as bad because of ads you should redo that little mistake you did and give it the stars it deserves. Its literally 2 dollars...
