I liked The Witness when the challenge was directly related to testing if you'd understood the rules or not. My favourite thing was where it deliberately exploited the fact that it knew you'd likely misunderstand a rule in order to redirect your thinking to the correct one. But it became frustrating when it appeared to introduce a new mechanic without any apparently priming (the colour filters in the greenhouse annoyed me). There were also a few puzzles which required near pixel-perfect positioning and orientation, which is one of the least fun things to do in 3D space and games need to stop doing it (I'm looking at you Horizon Forbidden West); others which required quite being able to pick up on quite sensitive audio differences. So as a whole, the game jumped from being highly rewarding to highly frustrating a little too quickly.
