I just don't get what's wrong with this to not be a Sonic 4.
It has great graphics, 2D gameplay, special stages, Boss Fights, fast paced platforming.. It's just like the old ones. I'm not getting what's wrong with it... Homing Attack could be great or awful. But until I try it, it just seems like a valid new gameplay feature, like spin dash was in 2 and flying was in 2/3 and power ups was in 3.
