Plankton

Plankton launched on October 27, 2016, and the developer was actively posting updates through early 2017. In the months after launch, several feature patches added new content: Steam achievements and a new chapter (November 12, 2016), container purchases and animated lamps (December 2, 2016), additional light devices (December 14, 2016), a Mac version (December 16, 2016), and a new container with a moving sprite (February 4, 2017). The last of these patches, on February 4, 2017, is the final update on record. Shortly after, on September 15, 2017, the developer announced they had published a new game called "Jellyfish," describing it as a potential "Plankton 2." This signals the developer had moved on to a follow-up project rather than continuing to develop Plankton. The store description does mention an intent to add more content "as an idle game with art style," but this language has not been accompanied by any actual updates since February 2017 — well over nine years ago as of June 2026. No roadmap, DLC, or further posts have appeared since then. The game appears to have reached its final state around the time the developer shifted focus to Jellyfish.
