good but not 'ALL MY 10 R' belong to this...
An amazing acheivement (hands you some kind of of medal)
On the more negative side of things there are only two major flaws with it.
First the sonic games are soo popular cause of the insane speeds the charcters can move at and on this version there was hardely any snece of that at all (although pretty good copying the rolling attacks). Also there was one other fairely annoying flaw; when a chracter loses rings the player normally gets a breather to catch their bearings by havng a couple of secods of invincibility and there was no sign of this here.
I assume these were the hardest things to program but apart from those flaws good job =D
