I'm finding the progression to be very smart - earlier levels felt more difficult actually because I wasn't accustomed to the way the developers set things up. I can't describe it too well, but as you keep solving stuff, you kind of know what to expect and have the idea of the what the solution might look like sooner, and you sort of work backwards from there.

If you want more puzzles, The Witness is also a great title. Although I found it to be downright maddening at times despite being able to beat it. I really like the variety of puzzles there, realy unique in that regard and its design. Hunting for secrets and extra stuff there takes lot, tol, though, but it's all so beautiful and rewarding.
