A faithful fun game with sonic premise of the first with a remastering of old levels of the early sonic very successful. A 3D relief that this gives a lot of depth to the game. A sonic scool old and new gen. The new gen is played mainly in profile view, in either it is not too interfere but fans of new sonic have the right to be disappointed with this approach. Mythical boss although the game is fairly simple. Some defects néenmoins. Starting with the life of the game that get too short (less than two hours to finish), an end boss rather difficult compared to the rest of the game, of little interest bonus missions, and a fairly limited multiplayer. In choosing revenche levels are interesting and very true to the original. A game that therefore 'more open to former Sonic fans who want to replay the first levels of the first generations. Enjoy
