Sonic is a game where the goal is to beat the level as fast as possible, which is why there are traps, obstacles, enemies, platforming, different paths, etc. It's like you people expect the game to be just "hold right to win" and are disappointed when that isn't the case.
That's the goal. In order to attain that goal the game is built around momentum. You gather momentum by running, spindashing, planning your routes, using the springs to your advantage, so on and so forth.
Nothing about the game is counter intuitive. Calling it counter intuitive is like calling any sort of whatever in your way in any game that you need to do counter intuitive. Games usually have challenges, it's not shocking that a game about maintaining speed has obstacles that get in the way of that.
It's fine to not like Sonic games, it's idiotic to pretend there's inherent flaws to it when it's play style doesn't suit you.
I think the main problem is the split second reaction that most other games dont expect you to have, not just that there is stuff in the way.
Think of a racing game. It still has a sense of speed while giving you a distance to see and work with whereas if it was like Sonic you could only see 5 feet in front of you and expected to make quick turns where you any hesitation would result in a crash.
So yes, it is a lil frustrating to be told to go fast, but not give people proper time to react to most things in a level. And if you think other games are like that, you are sadly mistaken.
