When I first heard that the hack was on Vizzed I really wanted to play it but I couldn't so I got the Sega Genesis emulator and the ROM and I started playing it.
GRAPHICS
The graphics in this game is really good Sonic,Knuckles and Tails look like the same sprites from Sonic The Hedgehog 3. The Sonic the Hedgehog 2 zones look pretty much the same as the original game.
SOUNDS
The track music in this game is the same as the original game it also has no bugs and it doesn't lag which makes it good.
STORY
Even though there are more characters in the game and the game-play is different the story is still the same as Sonic the Hedgehog 2 to stop Dr.Eggman (Dr.Robotnik) from taking over the world.
DIFFICULTY
The difficulty in this game is a lot easier because you can use Tails to fly to hidden places and areas where Sonic couldn't normally reach and you can also use Knuckles to climb walls and also to get hidden places.
OVERALL
Overall I thought that the game was great and I would like to play it more. The person that made this hack should be proud of him/herself.
