This game is nothing different from the original Sonic the Hedgehog. Except you get to play as Knuckles. Playing as knuckles is actually a fun experience. You can find more shortcuts with his glide ability and the spin dash that he can do is a really nice thing to have.

GAMEPLAY A: Not only can you do all the stuff sonic can do, but you can also glide and do a spin dash, which means that you can easily explore levels. The glide ability can get you across parts of the game that you can't stand here's an example. Are you tired of watching grass grow as you wait for the block in Marble zone to drag you across the river of fire. Well with Knuckles you can just glide through there and you can continue on with your game.

GRAPHICS A: I liked the graphics of the original game. It's colorful and the backgrounds take full advantage of parralax scrolling. In this hack, everything remains the same except for Knuckles. Hes is a more darker red color and he is fluidly animated. 

SOUND A: Nothing was added for sound. It is nice to hear those old tunes again.

ADDICTIVENESS B+: Like any Sonic game, this game get's me playing as long as I can until I beat it. That's a good thing.

DEPTH B-: Nothing added here, just the original 6 zones are in this game.

DIFFICULTY MEDIUM HARD: Knuckles cannot jump as high as Sonic can. Making some levels a challenge, same thing with the boss stages. It takes longer to beat them.

OVERALL RATING A
There was not much to say for this game because it's simply the same game except you can play as Knuckles.

I noticed one of your upcoming reviews is sonic cd. I play that a lot now, so I eagerly await to see  what you think of it.....decent review.

The game sound fun to play and easy because of your review but can't tell for sure until I play it for real.

G@mehe@d :   This is a very good review, It is better then my review of he game anyway. But this game is awesome! It's m favorite on vizzed and was the second game I played on the sight. I saw that you rated the game high on difficulty, I can understand this, but being able to fly over all of marble zone is very easy and should reduce the difficulty some, not to pick on you but that's just my opinion. Anyway great review and keep it up

P.S I can't wait for your sonic CD review, but if you are doing Parallel Worlds review WARNING: that game is VERY hardcore so watch out! But until next time see you later!

Bleh, it's an okay game to be honest. I prefer Knux in S3
