I will get straight to the point .I actually really enjoyed this game very much and the only time I actually felt frustrated was when attempting to beat the last 2 bosses.With that said what games dont need a little frustrated and strain to beat and actually accomplish something.It not only felt cool playing the oldschool sonic levels in 3d but left me wanting more after I beat the game.Something that would have made this game even more special would have been to get more playable characters like tails and knuckles  as well as more additional levels from atleast the first 3 games.All in all, for what it is its pretty great especially if you dont own any sonic games or miss the oldschool style and play of games like sonic rush & colors.
