This was certainly an experience. I love games with "organic" puzzles.

Baba is You
I didn't think the mechanic was impressive, but fortunately it was in the right hands. The puzzles are very well done, and the "latter phase" of the game is beautiful.
3
Return of the Obra Dinn
A breath of fresh air.
4
Snakebird
The only good mobile puzzle game. It is high on this list for being able to achieve good-puzzle-game status on such a platform. Kudos.
5
The Witness
Lots of good fun and interesting ideas.
6
The Case of the Golden Idol
This was really nice. The deductions and ahas are nice like in Obra Dinn, but it's also overall a different experience that can stand on its own.
7
Taiji
A fun witness-like.
8
Braid
Time shenanigan are always nice. Though I'm not sure how well the puzzles hold up today in my eyes.
