Nintendo's famous standards for quality were priceless feedback for the Bayonetta 2 team, the project's director has said.
Game director Yusuke Hashimoto has claimed that, while Nintendo has not blocked the team's ideas, the Wii U manufacturer has been thorough with its feedback.
"With all of the things we want to do in the game, [Nintendo] is not standing in our way," Hashimoto told Gamasutra.
"It's almost as if they are a very critical player that can sit back and give us great advice on how we're creating the game."

Hashimoto described Nintendo as a revered games creator that cannot be fooled on the core values of gameplay. The company's insight, he said, was unnerving.
"Working with Nintendo, one thing that comes out of that is that we're not able to cover up weaknesses in the core gameplay by making the graphics prettier or adding cut-scenes, or whatever.
"The concern, first and foremost, is the core of the game and the quality of the gameplay. They really have our back in that sense. And that's actually a little bit unnerving, working with people who are such perfectionists in that sense."
In September, Nintendo announced it will be publishing Bayonetta 2 as a Wii U exclusive. Months later, Nintendo president Satoru Iwata said the Bayonetta 2 release date was targeted for "2014", though did not specify any further.
The game's producer, Atsushi Inaba, said the partnership with Nintendo has been "really great".
"You have a certain image of a company, and in the case of Nintendo, we've found it's been really nice to actually work with them and find out what that's like."
