Director Yoshiro Kimura described the development process in a companion interview published the same day, revealing the team spent a full year on background art design with Katsuta and Kurashima, and that the initial Switch version launched with many bugs that were later patched. Kimura said the game was designed to communicate that \u0026#34;you don\u0026#39;t have to play perfectly\u0026#34; and that it is okay to live without scoring 100 percent. The music CD for the fictional RPG \u0026#34;Mikazuki\u0026#34; uses chiptune compositions, and the included booklet reproduces pixel-art game screens. The cloth map shows the world of \u0026#34;Mikazuki\u0026#34; as it connects to the \u0026#34;Stray Children\u0026#34; story.
