In order to ensure that the game was balanced, the designers had to play through maps several times to ensure that they were not unbalanced. Shimojo commented that once he became more astute at the game, it became hard for him to judge what it would be like for a novice to play, though he comments that his goal is to ensure that the difficulty level is right enough to allow the largest number of people to play it. Afterward, his comments are sent off to other staff members so he can be sure that he got it right. From then on, the game is sent to Nintendo's debugging team, who will then provide insight on the balance to the development team, who makes adjustments accordingly.
