Pretty good mod, you really know how to capture the feeling of speed with your characters! T.H. Sonic's left eye looks a bit too open, however. I think the air ability should be replaced with infinite flight since there isn't much with Super Sonic right now.
Honestly? I haven't any real problems with how he plays, but what I have a problem with is the way his quills look on his front and back sprites. Especially on the back sprites, I don't like how his quills are just completely stiff, and I dislike even more the awkward angle they're just perpetually frozen in.. And, well, the back sprites really matter on a game where most of the time you're viewing your character from behind.
OMG I LOVE IT SO MUCH NOW! i love that u added that one sound effect i forgor where it's from but i love the sound u play when u reach full speed, it's just so satisfyingly. and i love that u changed the player color as well, it used to look kinda boring tbh but DAMN i love it now. the only thing i would fix is the drop dash sprites, there isn't anything wrong with how they look but more on how it doesn't fit the rest of the sprites style. i'm actually currently playing it rn and i'm writing this review a but too fast for a full review, and there might be some things i haven't checked out yet, but this is just near perfection so far
While some of the sprites are okay, the character seems unfinished. There's a lack of polish for the running sprites, back sprites, etc, I can see blatant edits of the original sprites which makes this resemble Gamebanana addons.
What really proves this needed more time before public release is the fact that you get no real reward when you collect the chaos emeralds. You are not allowed to turn super, and even if you were to, there'd be a lack of proper sprites.
I can see the potential of this, but as I said this really needs more polish and time for it to be considered really good.
