Mashiroiro Symphony

The gameplay in Mashiroiro Symphony requires little interaction from the player, as most of the duration of the game is only spent on reading the text that appears on the lower portion of the screen, representing either dialogue between characters, or the inner thoughts of the protagonist. Every so often, the player will come to a "decision point", where they are given the chance to choose from multiple options. The time between these points varies and can occur anywhere from a minute to much longer. Text progression pauses at these points and depending on the choices that the player makes, the plot will progress in a specific direction.

There are four main plot lines in the original release that the player will have the chance to experience, one for each of the heroines in the story. This is increased to six plot lines in the PlayStation Portable version with the extended scenario for two female characters. To view all of the plot lines, the player will have to replay the game multiple times and make different decisions to progress the plot in an alternate direction. The PC-only Sana Edition contains only a single heroine's plot which is taken from the PlayStation Portable version's extended scenario and expanded further with new scenes and CGs.

The story of Mashiroiro Symphony primarily takes place in the fictional town of Kagamidai (各務台), which consists of two distinct districts dubbed the "Old District" (旧市街, Kyū-shigai), which primarily contains traditional housings resided by upper class families, and the "New District" (新市街, Shin-shigai), which is generally inhabited by working class families. The town also houses two private academic institutions undergoing a merger: the Yuihime Girls' Private Academy (私立結姫女子学園, Shiritsu Yuihime Joshi Gakuen), a notorious upper-class girls' academy nicknamed Yuijo (結女), and the Kagamidai Private Academy (私立各務台学園, Shiritsu Kagamidai Gakuen), a coeducation school which Shingo, the protagonist whose role the player assumes, attends. As part of the merger, students from both schools are selected to participate in a test class at the Yuihime Girls' Academy campus, an act which is initially opposed by the female student body.

Mashiroiro Symphony is the ninth title developed by the visual novel developer Palette, after their previous titles such as Moshimo Ashita ga Hare Naraba and Sakura Strasse. Mashiroiro Symphony's scenario was written by three people: Hozumi K, who wrote Airi and Angelina's storylines; Hare Kitagawa, who has previously worked on Minori's Haru no Ashioto, provided Sakuno's storyline; and Orgel, who provided Miu and Sana's storyline. Character design and art direction for the game was split among three people: Tsubasu Izumi, who worked on Feng's Akaneiro ni Somaru Saka, provided character designs for female characters; Tamahiyo provided designs for two male characters, Shingo Uryū and Hayata Mukunashi; and Nagomi Tozakura provided super deformed illustrations. Mashiroiro Symphony's music was solely composed by Burton, who provided music for Sakura Strasse. Tsubasu Izumi and Burton also work on Palette's thirteenth title Koi ga Saku Koro Sakura Doki, which was released on June 27, 2014.
