With Blow the devil is simultaneously in the details and at the meta level.
For example in the Witness, which I consider one of the best puzzle games ever made, you get a fairly simple core mechanic, but the game builds upon it in very interesting ways. It feels like a journey of learning and always challenges you in some novel way at each step. There are also several revelations along the way, where you discover new layers on top of the core puzzles.
I would expect that this new game will feature similarly careful design.
