Well if anything the developers wanted people to complete the storyline especially with the low amount that the surveyed did reach the true ending on the original. Kind of the reason why they implemented the difficulty options, so don't feel bad, they honesty just want people to be enthralled by the story...which the demo has none... XD
At least there was no microtransaction.
But now I have no idea if my more cautious style and different job choices were correct, or if the boss just had half the HP and lower attack stats.
