Better than episode 1. Lots of fun, great graphics and gameplay.
Graphics on the PC are very nice, cool lighting and shadow effects. Multilayer is pretty much dead since there are not people who log on regularly. If you want to play online you should try to arrange it with a friend or other gamer for that experience.
I played this game on my computer which was able to see the game at full resolution. If you are buying this game for a handheld device such as a smart phone, or small tablet beware the controls may be difficult. On the PC I used a XBOX 360 USB Controller.
I recommend it for the sonic "superfan" or just someone wanting to try out a 2D sonic game.
Replay Factor: B+
Multilayer: C- (Since no one is available for matches)
