39 Days to Mars is a co-operative 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.


If you don't want to play with your friends, the ship's computer-controlled cat will keep you company.


The mix of action and thoughtful puzzles make it perfect for playing in short sessions. The entire adventure fits comfortably into an evening.


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.

The HMS Fearful embarks for Mars soon!

Progress towards Mars


It's been well over 39 Days. Are we at Mars yet?

Development has been ticking away, and there has been significant progress since the last update at the beginning of the year! I've added new screenshots on the Steam page (don't forget to add it to your wishlist!). I'm wrapping up work on the gameplay, fixing major bugs, and in the new year I'll then be focusing on final polish and leading up to launch!

What's new?

Here's a quick rundown of some of the tasks I have been working on.


I worked on some transition effects between the levels and the puzzles. My aim was to continue the art theme by having screens look like they were sketched in and out using ink.


I cleaned up a number of old puzzles that were no longer used, and simplifyed some of the underlying code that had been in the game since the prototype and was no longer needed.


This monstrosity of an image shows all of the debug visualizations at the same time. I worked on a number of tools that I can use to track down problems and see what is happening in the levels. This has been a big help when balancing the difficulty of things.

Controls Again

This is the third iteration of the controls puzzle, and it is slowly becoming more comprehensible (while still maintaining the interest and incentive of discovery). I'll be running another playtest on the section of the game to check the results of the changes.


More flavor dialogue and small comments have been added around the game to give it more life.


The biggest new feature has been the addition of a singleplayer mode. Even though the game is designed as a co-op experience, I know that not everyone can find the equipment or time to play like this, and so I've been working on a way to play individually.


The solution was to add a ship's cat, who follows you around and will help out with the puzzles when you need a second hand. When playing with the XBOX360 controller, this will map to the second thumb-stick, and changes the challenge of collaboration between two people to one of collaboration between the your two hands!


What's Next?

I'll be tackling the unglamorous tasks of bugfixing and implementing the settings menus. I'll continue balancing the puzzles by playtesting at the end of the month.

Here's a snapshot of my to-do list:

I'd love your feedback!

Are you looking for a composer by any chance? I really like the theme of the game and I would happily produce classical/piano style music for free...

As I see, obstacles of game looks like Don't Starve (Somehow). Well, it's definitely interesting. However, what exactly must keep me playing?

For example, in Don't Starve I must keep lighted areas lighted, meanwhile my health, mind or hunger level can fall down and I should plan each day to survive without any loses. Otherwise, night will catch life of player.

I've yet to play Don't Starve, but the sense of pressure you mention is something I'm also hoping to capture in 39 Days to Mars. If you don't keep pushing forward with the puzzles & minigames, then problems compound and soon the ship is falling apart around you.
