You realize that you'll still have to solve the app puzzles to advance the narrative, yes? Do you think people will enjoy doubling up on puzzles?
You have raised a good point. What would be great would be if FFG added a Puzzle Solved button to the app so that players could choose to 'cheat'. This would enable players to substitute their own puzzles and to cheat if they really get stuck - and yes I am thinking of the 5 code mastermind puzzle which can take several actions to solve!
