Evaluation
39 Days to Mars launched on April 25, 2018 and received one major free content update — the "Additional Victorian Adventure" — on July 23, 2018, which added new puzzles and extended the story. The game subsequently came to Nintendo Switch and Xbox One in 2019, and launched on PS4 on October 29, 2019.
On October 29, 2019, the developer (a solo indie developer) published a post explicitly marking the PS4 launch as "the last major platform it will release on" and described it as "a strange, bitter-sweet feeling wrapping up development," adding that they "can't wait to continue on it with new and exciting projects." This is a clear statement that development on 39 Days to Mars is complete.
The final notable update came on April 20, 2020, when the developer added a cosmetic hat-selection feature tied to a newsletter signup — a small, fun addition rather than a content expansion. No further updates, announcements, or roadmaps have been communicated since then.
The game was designed and described as a complete, self-contained adventure that "fits comfortably into an evening." There are no unreleased DLC, no announced future content, and no ongoing update cadence. The developer has moved on to new projects.

About this game
39 Days to Mars is a co-operative (and single-player) steampunk puzzle-adventure game.
Step into the shoes of Sir Albert Wickes and The Right Honourable Clarence Baxter, two 19th century explorers who have chosen to pilot the HMS Fearful on its maiden voyage to Mars.
When the steam engine runs out of coal, the ship's cat shreds the navigation chart, and the tea gets cold, it becomes clear that interstellar transportation isn't a walk in the park. It will take the talents of two players working together on the problems that arise to get to Mars in one piece.
39 Days to Mars is a two player co-operative game.
The HMS Fearful is a masterpiece of unreliable engineering, therefore Albert and Baxter will need all the help they can get. Nothing can be done without the effort of both players, who have important roles to play in the adventure.
For the solo voyager, the ship's computer-controlled cat will keep you company. Without a second pair of hands, Albert will need an extra dose of dexterity to navigate the challenges of Victorian space flight.
The mix of action and thoughtful puzzles make it perfect for playing in short sessions. The entire adventure fits comfortably into an evening, or a long tea break.
Be drawn into the world of Albert and Baxter by the unique illustrated artwork. 39 Days to Mars has a rich sound-scape and a beautiful piano score that is punctuated only by the occasional disaster.
