I've watched through the main missions of all of Zone 1 and Act 1 of Zone 3 and this looks...serviceable. Level design seems to have adequate branching paths and I saw the player fling themselves between areas over bottomless pits at certain points rather than using the rails to get around and I appreciate that choice, but the level design doesn't seem to do anything particularly interesting. Not really getting the "this is the best 3D Sonic game since Generations" vibe that some people are putting out over this. Also I really loathe Knuckles and Rouge only being able to climb designated walls. Final Horizon obviously does this too and it just feels so cheap and railroaded when there are so many other ways to show players the intended approach without restricting the ability like that.
