The automatic movement of perspective enabled the game to have 3D environments while maintaining simple controls, and clever Wiimote movements like pointing at the screen to explore in 3D allowed the team to avoid "resorting to the Nunchuk," as producer Yoshio Sakamoto called it.
At the same time, Sakamoto wanted the story and action to blend seamlessly, so the team worked with video production company D-Rockets. Director Ryuzi Kitaura described creating detailed storyboards to impress Sakamoto: "I think I drew more than 300 storyboards in total. The image count was over 2,000. By this stage, I was also accounting for camera work and action, so they became really elaborate production storyboards. I think I took over six months to finish them."
