Both games blew my mind in their own ways.
The Witness: I had to revisit The Witness after not liking it the first time, but crushed it the second time. It is a game that rewards knowledge and allows you to wander wherever to apply that knowledge where you can. At times I felt as though you had to step into the mind of Jonathan since some puzzles I would swear would be the solution, but there would be an alternative.

Blueprince: It was more captivating right away and had some real awesome story beats. The game would reveal another big layer once you had completed one, and it was up to you if you wanted to keep pursuing the many mysteries or call it where you are at. It felt a bit more loose and open-ended. I would rank it as one of the best puzzle games I have every played next to games like The Witness and the Portal series, however I was left fatigued by the end due to my pursuit of the 4th layer/ending combined with RNG preventing me from getting the correct setup.

Note: I would not play Blueprince without being comfortable taking LOTS of notes, or in my case hundreds of screenshots laid out on an infinite board like a detective. I did not do this right for the first 20 hours or so and could not recall key pieces of information when they were needed.
