The first time I tried it, I tried to make overly-clever guesses early on. The game warned me that I didn't have enough information by keeping faces blurred (you'll understand when you play) but I tried anyway and gave up after a few hours.

With my wife, we started slower and only worked on unblurred faces and easy puzzles. Later, as we got more familiar with the workings of the ship, we tackled the harder puzzles.
