Later in the interview, Nintendo producer Hitoshi Yamigami described the difficulty of working with Treasure on the first Sin & Punishment, given, well, the difficulty of Treasure games. "When I said, 'It's too difficult. I can't do it," they responded, 'Then you're not good enough to be in charge of this project.'" It took about a year for the team to finally determine that Sin & Punishment was, in fact, too difficult.
For Star Successor, Nintendo's Yurie Hattori joined the project and initially found it too difficult as well, pushing to make the game more accessible. While she did prevail upon Treasure to streamline the experience with a tutorial, she eventually discovered the Treasure fan within her and ended up recommending that the difficulty be increased.
