Impossible Quest

Impossible Quest launched on June 3, 2016 as a text adventure. The developer shipped one notable content update in late October 2016 — a Halloween-themed quest called "Spooky Scary House" with 13 endings and 4 new Shadow Endings. This appears to have been the sole post-launch content push, and it was covered across two news posts on October 26–27, 2016. Of the 28 developer news posts on record, the remaining 26 are sales, discounts, or low-signal items — no further content updates, no roadmaps, and no announcements of future content. The last substantive developer communication was in October 2016, nearly a decade ago. There is no DLC listed and no unreleased content on the store. The game was released as a small indie title with limited post-launch development, and all signs point to it having been complete since October 2016.
