Morphine

Morphine is a story-based indie adventure game that launched on October 28, 2015. Developer activity after launch was minimal: a bug fix patch was released on November 5, 2015, and the only other notable post (June 17, 2018) was a promotional announcement for a bundle with other games by the same developer — not new content for Morphine itself. The store description contains no mention of planned DLC, expansions, or ongoing updates. No DLC has ever been listed for the game. The developer has made no communication of any kind since June 2018, and no future content has been announced at any point. This game appears to have launched as a self-contained, finished product, and all available evidence points to development having concluded at or shortly after its initial release.
