I'm not sure that's entirely true.

I'm getting "bring your adventure" vibe, similar to The Witness.

Take Thomas Was Alone for example - seemingly simple platform puzzle game with deep and engaging story where you're more interested about characters than new mechanics and puzzles.

In contrast The Witness could be scraped to core puzzles and released as an iPad game for $5.99, but the whimsical island and scattered pseudo intellectual voice clips make it so much more giving you opportunity to pause and think about life.

This seems very similar. A sokoban puzzle game with an entirely optional plot line that leaves a lot for interpretation by the player.
