Im in act 3 and only encountered the "you're underleveled" message once at that same point. I havent scoured the areas for everything nor speed run the main story. I think act 1 is tight like you said, but it seems to be much looser as you progress.
I second 'The Witness'. Its a great game and the puzzles get very interesting as you progress and begin to understand the world you have been thrown into.
There was an episode of Orville that explored that very thing.
