oO

oO launched on July 6, 2015 as a self-contained hardcore arcade game. The developer added Linux support and achievements on August 24, 2015 — the last meaningful update to the game itself. Since then, the developer's posts on this game's store page have been announcements about separate, unrelated games (Hook 2 in July 2022, and Overwords in July 2025). There is no DLC, no roadmap, no announced future content, and no post-launch content cadence for oO itself. The store description explicitly frames the purchase as supporting the developer's future projects rather than promising additional content for this game. oO shipped as a complete, finished product.
