The abilities aren't fun, or original, and have been recreated thousands, if not, millions of times. Sonic's ability is basically momentum flip in a nutshell, Tails's ability is basically a higher jump, but in a different state. The glide stomp is... i mean... it's a stomp, but when your gliding. Amy's ability... like i said, not original, but its also not fun, and is really buggy for me. And why do you have to do custom 1 to do almost every ability, when there is other keybinds, like knuckles stomp can be spin. And amy's can also be spin if your holding it on the last frame. Metal sonic's ability is a jump thok mixed with a float, which is okay, but i barely ever actually float when doing it, and just use a thok. I don't even know why metal has a thok anyway, cause metal's ability should be jump-thrust. The metal sonic ghost is only for one color, blue. and fang's bounce boost is overpowered. This mod has a lot of potential, but it missed. I forgot to say that the double jump can still hurt enemies yet you are uncurled.
