I have enjoyed the sonic series since it came on the Sega Mega drive. For me this game had good graphics for a 2d game and was well presented. Sonic has been a popular character and is main good guy players get to play in the game. As usual Dr egg man wants to capture the world and has kidnapped the friends of Sonic and Tails, and will have to release them and than can play as them.
The characters you rescue have some abilities which help in the quest, they don't differ too much in gameplay as Sonic and Tails. The one I like most is knuckles he used to be bad but changed, and they continually taunt each other king of like Goku and vegeta in the Dragonball z series it is funny how they do that. Knuckles is stronger than sonic in strength.
The music can be irritating at times, this was common in most games in 90s and graphics is real good and enjoyable. I enjoyed the controls which were easy to master and learn. A game which has good controls makes it more easy to play and have fun.
Collecting rings is a common theme in the sonic games and easy to do, most of the time some times can be hard. Usually it is easy to see what traps are in place and how you have to avoid them to get to the rings. The boss fight was real good and as usual Dr egg man has many ways to harm the player in the fight.
