Marble Duel: Sphere-Matching Tactical Fantasy

Marble Duel launched on November 12, 2015 and received a series of level-pack updates over the following years: a Windows content update in June 2018 adding 15 new levels and new content, another batch of 15 levels in September 2019, 15 more levels tied to a Lunar New Year theme in January 2020, and a final update of 16 new levels in July 2020. Since July 27, 2020, HeroLabs has posted no further updates, patches, or announcements for Marble Duel. The post from May 2024 tagged to this game's news feed was actually a promotion for a separate, unrelated title (Union of Gnomes: Prologue) — it contains no mention of Marble Duel and carries no implication for its development status. There are no unreleased DLC listings, no roadmap commitments, and no developer statements promising future content for Marble Duel. The game's content development appears to have concluded with the July 2020 update, nearly six years ago.
