Diatomic

Diatomic launched on June 24, 2024 as a self-described complete product. The store description explicitly states "Diatomic is Complete" and lists a fixed set of content: 30+ levels, 70+ weapons, 20+ enemy types, boss fights, and agility challenges. Following launch, the developer shipped two feature patches — an easy difficulty mode and boss balance adjustments (June 30 and July 24, 2024), followed by a more substantial update on August 18, 2024 that added 26 Steam Achievements and an Endless Mode. That August 18, 2024 update is the last recorded developer communication. There are no unreleased DLC listings, no announced future content, and no roadmap pointing to upcoming updates. The developer has made no posts since August 18, 2024, which is consistent with a game that shipped as a finished product and received a short post-launch polish cycle before going quiet. The "Diatomic is Complete" language in the store description, combined with the absence of any further communication since August 2024, points to this being a finished, self-contained game.
