不落城-Unconquered Castle

Unconquered Castle (不落城) released on October 12, 2018, as a Visual Novel/SRPG hybrid. Its only paid DLC — the original soundtrack — launched on November 21, 2018. In April 2019, the developer announced a content update adding a new strategy stage and UI improvements, which shipped on May 13, 2019. That update appears to be the last content work done on this game. After May 2019, the developer's attention shifted entirely to a new title: they teased a new game called "hallucination" in October 2019 and announced its full release on June 1, 2021. There have been no further posts, patches, or announcements for Unconquered Castle since May 2019. The developer has made no mention of any additional content, expansions, or updates for this game. The one DLC in the store listing is fully released. All content for the game appears to have been delivered by May 13, 2019, and the developer has since moved on to other projects. The game can be considered a complete, finished product.
