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!

I've been working on 39 Days to Mars in my spare time and posting development updates here on IndieDB for a long time. Four years, two months, and 22 days to be exact.

Over 2,700 hand-drawn art assets.

Exactly 13,318 lines of code.

And now 39 Days to Mars is finished, and releases today. You can buy it on Steam, Itch.io, or Humble Store, and it launches with a 20% discount!

And to give you an idea of the wonderful chaos you're about to embark on, here's the gameplay trailer!

For everyone who has been watching this development journey, who have commented, shared, and given me support : Thank you! I hope that 39 Days to Mars is as exciting and fun to play as it was to make.

And if you're not quite ready for an adventure, you can also add the game to your steam wishlist to be reminded when it releases, or join the discord to chat with us about the game.

Happy sailing!

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.
