Honestly I don't really have anything to complain about, it's fine. Kinda feels a bit more like Sonic 1/2 then what I would've preferred (3, & Knuckles, or Mania). Level variety is nice, but camera is far too zoomed in to see where you are going and levels lack a lot of landmarks to make them memorable outside of the boss areas. But the level mechanics are varied enough to be interesting. I like the bosses in concept, but they are still kinda annoying to fight with a lot of wait your turn for hit moments.
