A side note, if you've played The Witness but not yet The Looker[1], you probably have been missing out.
I quite enjoyed The Witness but The Looker was just great.
I played The Witness and didn't find it remotely fun. I've enjoyed all of Blow's other titles.
I suppose I was coming in with expectations of a modern Myst and/or Riven, but it was not that.
There was not enough active narrative to keep me engaged with the puzzles and there wasn't enough "reward" in completing them.
I ragequit the Looker when it spawned an apple in the snake game inside my snake.
The Looker is quite possibly the greatest parody ever executed in a video game. It creates the same kind of "ahah" moment that games like The Witness do, but in a way that really pokes fun at the level of pretentiousness those games tend to indulge themselves in.
