Evaluation
Undernauts: Labyrinth of Yomi launched on November 4, 2021 as a complete dungeon RPG. Following launch, the developer shipped a series of bug fixes and minor patches through June 30, 2022, addressing text display issues, controller support, framerate behavior, and Steam Cloud functionality. There are no DLC listings, no expansion announcements, no roadmaps, and no developer statements suggesting additional content was ever planned beyond the base game. The store description presents the game as a self-contained experience. All post-launch activity consisted purely of maintenance patches, and developer communication ceased entirely after June 30, 2022. The game launched as a finished product, and the post-launch patch activity confirms it was treated as such.
Evidence

Store description presents the game as a self-contained dungeon RPG with no mention of DLC, expansions, seasons, or ongoing content updates.
