"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: A Space Adventure. 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 in 2 years. It has been envisaged as an experience, an interactive story based on exploration and logical puzzles. The game is made of static pictures with video transitions, and has a lifetime of 10~30+ hours.

If you buy the game here on itch.io, you'll have the possibility to request a free Steam key (please note that there is a limited quantity of keys: I'll have to update the list manually if all the keys were requested, which can take a few hours or days. When there are no remaining keys, you will be able to try again later, when I have added new ones).
Catyph is also available for purchase on Steam and Humble Store.

This game is difficult and requires a pen and a paper to take notes. A walkthrough is available here.
Download Update 1.2 separately.
