Natsu no Iro no Nostalgia

Natsu no Iro no Nostalgia (追忆夏色年华) is a visual novel originally developed by MOONSTONE in 2015 and released on Steam in its international Chinese edition on December 6, 2019. It is a self-contained story-driven romance game with no DLC, no expansion content, and no post-launch content updates of its own. The developer news associated with this Steam page is almost entirely focused on a separate MOONSTONE title — 《来自昏暗的时间尽头》 — which was announced in November 2020 and released on December 17, 2021 through the publisher HIKARI FIELD's own storefront. These posts appeared on this game's Steam news feed because the publisher uses it as a communication channel for their broader catalog, not because they indicate any additional content for this game. The game itself launched as a complete, finished visual novel. There are no unreleased DLC entries, no roadmap, no developer statements promising future content for this title, and no post-launch update pattern. The last developer communication specifically about this game was its release announcement on December 6, 2019. The store description confirms it is a fully packaged product with 36 achievements and cloud save support — all features of a finished release.
