but whose development time seems to me just unsustainable.
This is the problem.
At some point in Part 1, the game felt stopped.
And on the last day of Part 1, when the developer solved several characters, I saw it and felt that the developer had changed the plan.
Of course, it may be my illusion, but slow working speed, small volume and long term always test consumer patience.
And in terms of the story, there's nothing different from Part 1.
For now, part 2 is meaningless than dividing the capacity of part 1 and this is the first time I've played such a game.
Usually, developers divide parts for new stories or divide parts to inform the story's rapid progress.
