Aoki ultimately produced "Chrono Trigger", while director credits were attributed to Akihiko Matsui, Yoshinori Kitase and Takashi Tokita. Toriyama designed the game's aesthetic, including characters, monsters, vehicles, and the look of each era. Masato Kato also contributed character ideas and designs. Kato planned to feature Gaspar as a playable character and Toriyama sketched him, but he was cut early in development. The development staff studied the drawings of Toriyama to approximate his style. Sakaguchi and Horii supervised; Sakaguchi was responsible for the game's overall system and contributed several monster ideas. Other notable designers include Tetsuya Takahashi, the graphic director, and Yasuyuki Honne, Tetsuya Nomura, and Yusuke Naora, who worked as field graphic artists. Yasuhiko Kamata programmed graphics, and cited Ridley Scott's visual work in the film "Alien" as an inspiration for the game's lighting. Kamata made the game's luminosity and color choice lay between that of "Secret of Mana" and the "Final Fantasy" series. Features originally intended to be used in "Secret of Mana" or "Final Fantasy IV", also under development at the same time, were appropriated by the "Chrono Trigger" team. According to Tanaka, "Secret of Mana" (which itself was originally intended to be "Final Fantasy IV") was codenamed ""Chrono Trigger"" during development before being called "Seiken Densetsu 2" ("Secret of Mana"), and then the name "Chrono Trigger" was adopted for a new project.
