Project lead Kazuyoshi Osawa, for example, said he "agonized" over the DS control scheme for about six months. Apparently, he wasn't exaggerating -- other team members noticed. "Yeah, he was in grueling agony for quite some time," said Kou Takeuchi. Osawa said that Masami Yone helps him cheer up by sending him pictures of kittens (an unauthorized use of company e-mail for which the two were semi-jokingly admonished by Iwata).
Oh, and there's also a lot of discussion of the Game Boy Advance, arcade, and DS games and their development, including details of producer Tsunku's involvement. But the adorable interaction between the team is the real draw here.
