Evaluation
Haven Moon is a self-contained, story-driven puzzle adventure game released on July 8, 2016 by solo developer Francois Roussel. It launched as a complete, finished experience with a clear beginning and end — there was never any roadmap, DLC, expansion, or post-launch content promised. The store description frames the game as a polished, balanced single experience with no mention of additional content.
After launch, the developer made a handful of quality-of-life improvements: a v1.1 patch on October 26, 2016 improving visuals and UI, a v1.2 update on September 7, 2017 adding WASD controls and puzzle hint adjustments, a v1.2.1 cleanup on November 14, 2017, and a v1.3 update on January 23, 2018 adding Steam achievements by popular request. The last known update was a minor bug fix (v1.3.1) on May 14, 2019. None of these updates added new story content — they were all maintenance and quality-of-life improvements to the base game. There is no DLC, no season pass, no announced future content, and no developer communication suggesting anything further is planned. The game shipped as a complete product and remains so.

About this game
Haven Moon will transport you to a mysterious world where you have to explore abandoned islands and solve their secrets to find a treasure. In this Myst-like game inspired by Jules Verne’s universe, use your senses and intelligence to find your way through secret passages and curious machinery.
From that, you'll have to explore the islands on Seleos to discover who was Ektor Turren, what happened to him and to his world, where to find the treasure and how to go back home with it.
You can take all the time you want to explore and solve the puzzles. No one will come bother you here. The puzzles are neither too hard nor too easy, just like the length of the adventure is neither too long nor too short. Everything has been balanced to provide a relaxing experience and pleasant time spent in an imaginary world.
The puzzles that you will encounter in Haven Moon are completely integrated into the environment and in perfect harmony with the story. They have been designed with great care to give a natural and intuitive user experience.
Very simple and intuitive interface
The game has been made to be accessible to all kinds of players. The interface and controls have been carefully designed to be as simple and intuitive as possible, featuring a mouse-only gameplay: the entire game uses mouse navigation. Move it to look around, left-click to move forward and interact, and right-click to move backwards. That's it!
(For those who prefer WASD style controls, it's still possible to configure keyboard controls from the input menu although this is contrary to the game design).
High quality graphics
Haven Moon features high quality 3D real-time graphics, offering complete freedom of movement in a detailed and realistic environment.
(A "light" option can be used to play the game smoothly on computers running on minimum system requirements).
High quality original soundtrack
To bring a fascinating mood and beautiful emotions to the game, Hollywood composer Leo J. Russlan exclusively composed a wonderful orchestral cinematic music for Haven Moon, making the experience even more captivating.
A game for everyone
Haven Moon is a tranquil game dedicated to contemplation and reflective thinking. It's a calm and solitary place where you hear the sounds of the sea, the wind and the beautiful music. You have all the time you want to explore and solve the various puzzles.
This project represents not only 3 years of real hard work, but also a huge part of my life. The journey leading to the release of this game was incredible.
I absolutely loved working on Haven Moon and I was very lucky it turned out exactly the way I had imagined it. So now I really hope that you will have as much pleasure playing it as I had creating it.

20 YEARS IN THE MAKING
It took me more than 20 years to create this game. From the first time I played Myst sometime between 1994 -1995, when I was a teenager, recreating the same experience has become an obsession. During all these years, I have tried many times to build my own Myst-like game, but it's only 3 years ago that everything coincided to make Haven Moon possible.This project represents not only 3 years of real hard work, but also a huge part of my life. The journey leading to the release of this game was incredible.
I absolutely loved working on Haven Moon and I was very lucky it turned out exactly the way I had imagined it. So now I really hope that you will have as much pleasure playing it as I had creating it.
