Boïnihi: The K’i Codex is, in the pure tradition of the Black Cube series, an exploration game where solving puzzles requires observation and learning the codes of the world. Created by Simon Says: Play! (ASA, Catyph, Myha...) and magnified by an oriental-sounding music composed by Yazorius, Boïnihi has a gameplay never before seen in the series, halfway between Myst-like and traditional adventure games.

A game by Simon Mesnard  https://linktr.ee/simonmesnard

"An astronaut has been wandering through space for 4 years, and finally landed on an uncharted moon, where a mysterious hermit used to live alone. Boïnihi was his name, and he was one of the rare survivors of a terrible event known as "Day Zero", which happened long, long ago..."

Boïnihi is an independent and self-funded game, mainly created by one person. It has been envisaged as a 1st person adventure with a hybrid gameplay (3rd person camera). You will go through an exotic story based on the exploration of a faraway moon and the solving of didactic logical puzzles. This game is reminiscent of the Myst series but also point and click games like Syberia, The Longest Journey...

English and French (DRM-free)

Additional Bonus folder included in this purchase (mp3, video, dvd cover, comic book...)

Boinihi is also available for purchase on Steam. For several reasons I have stopped giving Steam key, so choose where you prefer to buy.

This game is quite challenging and requires a pen and a paper to take notes.

Original release date: May 27th, 2020

The beautiful SciFi soundtrack of BOINIHI was composed by YAZORIUS and is available for free in streaming. 



Hybrid gameplay, between 1st person adventure (Myst, Rhem...) and 3rd person (Syberia, etc.)
Please note that a large part of Boïnihi is played with mouse, however moving the character is closer to what you could see in Grim Fandango and so playing with keyboard is mandatory (arrows or WASD). Visit the regions of the moon of the hermit, take notes on a piece of paper, and solve the puzzles!
