I was "puzzled" (ha!) by the game world.
In previous puzzle-driven games I have played, the game world provided a narrative and a context for the puzzle. Myst Island, #OuterWilds. Even Braid! Solving the puzzle allows the player to interact with the that world, and the narrative within it.
On the opposite end of the spectrum is a #Sudoku puzzle book. Puzzles don't exist in a narrative context. Solving the puzzle simply means you've solved the puzzle and can progress to the next.
