Baba had already given his approval for the project by then. In addition to Maeda and Suzumoto, Takashi Ishikawa is also listed as one of the main scenario writers. Scenario assistance was provided by Kai, Tōya Okano and Tomotaka Fujii. In terms of gameplay, Air was designed to emphasize its story compared to its adventure game elements, with the development team opting to include very few choices to diverge the plot, which Maeda later regretted. According to Suzumoto, some players complained that Air did not feel like a game as a result, and that some found it boring because of a lack of these choices. Three heroine routes were developed to show a range of different possibilities the player character Yukito Kunisaki could take in parallel universes. In doing so, Maeda wanted to show that small variations can diverge Yukito's ultimate fate. In the planning stage, Maeda did not specifically include adult content due at least in part to his self-described inability to write detailed sex scenes. Maeda believed that people would have bought the game even without adult content, but he noted that this would have been impossible in the past. Suzumoto pointed out how most of the sex scenes in Kanon could be avoided, and although this is similar to how Air is structured, Suzumoto was one of the writers who made it so that at least two sex scenes in Air would be unavoidable. Itaru Hinoue is the chief artist and character designer for Air, continuing from her position with Kanon. Further computer graphics were split between three artists—Miracle Mikipon, Na-Ga, and Shinory—and background art was provided by Din and Torino. The game's soundtrack was composed by Maeda, Shinji Orito and Magome Togoshi, who had started working with Key since before Kanon release.
