He also likes to create a stage in which the goal is clear, though being able to finish the level won't be so easy. He also wishes to create a perfect balance so that while the game will be hard, it won't be too hard that the player will get annoyed and quit. He played the role of director (along with two others) on Mario Kart: Double Dash‼ and assistant director on Donkey Kong Jungle Beat. Recently he designed many of the planets and levels featured in Super Mario Galaxy. His interview with Satoru Iwata in Iwata Asks regarding the game revealed a lot about his past and his current goals.
