Like someone pointed out before, yeah, while in the air, Sonic's like just fucked, lol, if you jump while moving in a direction, unless you cancel the momentum with another short hop, you just careen to the ends of the world, lol.
But aside that, I feel Sonic's controls pretty well, I can do donuts while going at my current max speed, didn't even knew there were options to toggle his movements even more, think that's a first that has been done officially.
I do agree the first world looks quite bland and boring (still in it, stopped playing after a giant black fucker yeeted Sonic into the distance), with just mostly empty green hills (heh) and some broken structures with random springs, boosters and rails around... Not maybe an amazing first impression, but I'm still kinda enjoying running around in it, tho you can't really "gotta go fast" if you wanna uncover all the secrets and such, it's more of a stop and go, mh. But I would blame that more on the structure of open world games rather than being a "bad" Sonic game or the devs being incompetent, BotW was the same more or less, open world games are by design just big and empty, meh.
Perhaps if the world was more Sonic-themed it would've been nicer to run around, but eh, went with another "Sonic's lost in another world" plot or what.
Fighting the enemies it's either braindead or kind of fun, Sonic's got some dumb but fun moves to play around with, and the enemies that don't just go down with one hit are fun to mess with said moves, tho you can beat most by just using the combo you start with, kinda. The shrine-classic levels are a small break from the like "boringness" of the open world, and I had quite a bit of fun beating 1-2's "finish in 55 seconds" challenge, with having to work out shortcuts and quirks in the physics to go as fast as possible, think I now know how a speedrunner feels like, lol. From what I read here tho, seems it's the only one that is somewhat challenging? Would be a bit of shame if it is, mh. Also, by completing said shrine challenges, you get a ton of keys for them chaos emeralds, and, like... already can get 4 I think, if am getting the rest so quickly as well... like, wat.
I do hope they don't do something like "oops, you lost the emeralds when moving on, get them all again", or that would be effing stupid.
