I’ve never played the game (hope to soon), but I’m guessing each chapter of the game is unique and a completed save lets you select any chapter. Once you’ve solved the puzzle (especially if solved recently) solving it again is quick.
So even if you were halfway through chapter 3 in your own game, a completed save file will quickly return you there.
Why would anyone want a completed save for a game that has basically no replay value once completed…?
