the game has a terrible gameplay. the levels aren't even that good. i literally regret on wasting money to think that game. and the knuckles/rouge stages? don't get me started on that crap. the game is a 8/10. the gameplay is bad and the worst thing are the knuckles/rouge stages. even SA1/SADX is better over it. i played SADX from the steam store and i can tell that for the people who didn't even play the game to play it instead of saying "oh, it's so fire". some may regret and some may not. and i don't care about shadow. for me, he should never have been existing.
