Eh... over rated
Not saying its a bad game, but NG calling it the "best flash game ever" is a little bit... WRONG!
First, the controlling sucked, it didn't respond like a sonic game should. If you jump, you can barely control the curv of the jump.
Secondly, why the hell can't Knuckles glide? He's supposed to be able to glide, and also climb walls.
Finally, I was impressed by the music. It gives a true nod to the classics. I hope to see more of your works, but try to improve upon the above problems. ^^
