Evaluation
MOLEK-SYNTEZ launched on November 19, 2019 as a complete, self-contained puzzle game. In the weeks surrounding launch, Zachtronics shipped a series of polish patches and added a community-sourced bonus campaign — all of which shipped within days of release and were clearly part of the game's launch window content. There have been no updates of any kind since that period.
The most significant post is from July 5, 2022, where Zachtronics announced Last Call BBS as "the last game by Zachtronics," explicitly signaling the studio's retirement. This is an unambiguous statement that the studio has concluded game development. No further content for MOLEK-SYNTEZ has ever been announced or hinted at, and the studio that made it is no longer actively developing games.
MOLEK-SYNTEZ launched as a finished product and has been complete since its release date.
Evidence
Zachtronics announced Last Call BBS as 'the last game by Zachtronics,' explicitly marking the studio's retirement from game development.
Bonus campaign shipped as a free update shortly after launch, completing the game's planned content.

These walls don’t do a damn thing to keep the cold out.
I should go outside and walk.
Instead, I light another cigarette and keep working.
