Catyph: Light Edition + Kitrinos both available


I've spent a terrible lot of time on the Black Cube series since the beginning of the year, but I think it was really worth it.

First of all, for the 2 years anniversary of the release of Catyph, I have recreated the game.

Please welcome Catyph: Light Edition
a kind of director's cut or remastered, with many small but interesting changes. I hope you'll like it, I've put a lot of efforts into it. The good news is it's completely free and should appear in the form of an automatic update. A new Launcher will allow you to choose between the Light or Original Editions of the game. Please be careful when you choose that your previous saves will not be compatible between the 2 versions.

I've spent a lot of time on Catyph Light Edition and have involved some good friends in testing. However it remains a game developed by a single person and beta-tested by only a very small team, and as a result there might be some remaining issues that we totally missed. The whole game works well, we could all finish it several times, but since it was entirely recreated, it's not impossible to discover a few hidden bugs. Please notify the problems so that I can try to fix them asap. Thanks!

Finally, in case you didn't notice this, a new game in the Black Cube series (ASA, Catyph...) was recently released on Steam too! Kitrinos: Inside the Cube is totally free (F2P) and will take you in a mysterious prequel to the other games for a 2~3 hours adventure in a strange scifi world. It comes with a nice DLC (OST, Piano arrangement, artbook).

Please take a look at Kitrinos, and if you like it, don't forget to leave a review and spread the word! Many thanks to all, enjoy the games and have a great Summer holiday!

Black Cube news

Hi everyone!

Catyph: Light Edition is finished and currently in private Beta Test. If everything goes well, this modified version will be available somewhere in July.
You can still see the list of changes here:

Catyph LE will be free if you already purchased the original game and should be downloaded as an automatic update as soon as it is released.

You may also be aware that we recently released a nice short game called Kitrinos: this free adventure is a prequel to the Black Cube series, and will be published on Steam around July 16th. Yes as I said it will be free! You can already check the page here:

Last but not least, I have finally paid the submission fee for Myha: Return to the Lost Island (successful Kickstarter last year, thanks to everyone). The game makes good progress and we hope that you didn't miss the private playable demo if you had chosen this reward.

Next I plan to finish my work on Boïnihi: The K'i Codex, the next game in the series.

You can learn more about all these games on the official site of the series:

All existing Black Cube games will thus be available together on Steam within a few months. They are all DRM-free, and you can currently benefit of -25% on ASA and Catyph during Steam Summer sales:

Thanks for your support during all these years!

“Catyph is the sequel to ASA: A Space Adventure, and is once again mostly the work of one man, Simon Mesnard, who is the game’s primary designer, artist, writer, animator and programmer. I’ve played ASA, and as solid as that debut adventure was, I found many improvements this time around. The environments are larger and animation now brings them to life. Navigation is smoother and the voice-overs are more engaging, particularly those of Germinal and Lantier. [...] It took me almost 35 hours to finish this game, and by the time the credits launched, I really did feel as though I had been on a space odyssey.”
4/5 – Adventure Gamers

“If you’ve never played any entries in this series and are wondering if it’s for you, look no further than its inspiration. Do you like first person explorative games such as Myst? If so, it’s for you. If not, I can’t recommend it, as this isn’t some sort of fusion game with another genre. What’s in store for those of you that enjoy the genre though, you’ve got a lot to look forward to in your exploration.”

About This Game


"In 2062, Men from Terra have access to a new technology from a mysterious Black Cube they found 5 years before. With this new power, they decide to explore their solar system, in search for signs of intelligent life. They send you at the discovery of planet Catyph and its moon Tytaah." CATYPH: The Kunci Experiment is Another Space Adventure reminiscent of Myst and Rhem, and you can absolutely play it without knowing anything about the first Black Cube game, ASA. With the help of the data that you collect on Tytaah, you must attempt to access the 7 regions of this moon. Your main mission: understand what the Kunci is. The whole game relies on observation, discovery and exploration.

CATYPH is an independant and self-funded game, mainly created by one person. It has been envisaged as an experience, an interactive story based on exploration and logical puzzles. This prerendered 3D game is made of static pictures with video transitions.
