In this 2D platform game that mixes exploration and logic, you are Octo, the amnesiac octopus. You’ll discover wild planets with him, inhabited by strange and evolutive flora and fauna. You’ll meet quirky characters, and gather clues to help Octo recover his memory. You’ll learn to move around and to evolve in a new and chaotic universe, as well as to avoid the traps that stand in Octo’s way to disorientate him.



Octo is a scientist, and is curious about everything. His rocky spacecraft takes him here and there throughout space, where the deepest mysteries can challenge his extraordinary intelligence.

Yet, Octo is no longer in the first flush of youth… And his eight tentacles aren’t as alert as they once were. To assist him in his old age, he travels surrounded by his loyal Octobots ; Robots of his design which help him to move and give him « superoctopusian » abilities.

His whole life is to take a new twist when, during a mission, Octo suddenly looses control of his ship, and crashes on an unknown planet…

The octopus survives, but doesn’t remember anything. Neither who he is, nor where he is and where he was going… Even worse : the violent impact scattered his octobots all around the galaxy. All but one. To go back to space, Octo is therefore going to need to explore this new, strange and colorful world, in order to find his dear robots that will be able to repair his space ship once they are gathered.

But what is this place? What trials and tribulations can our hero expect? Where are his Octobots? And what mission might have driven him around this bizarre planet?


Developed in C++ for PC, Mac and Linux, An Octonaut Odyssey is the result of a work done by a team of enthusiasts. The game is unique mainly because it was entirely designed based on a simple SFML library, from the physics engine to the music, including animations and sound design.

The different elements of the game are partly procedurally generated. The sceneries and the relief are the results of mathematical algorithms, that make of each and every planet, a unique and evolutive living place.

An Octonaut Odyssey has much evolved from the beginning. Originally a simple student project for the information-technology school « 42 », it became little by little a much more ambitious and personal project.

"Let yourself go with the psychadelic poetry of An Octonaut Odyssey." Tracks Arte

"If Pink Floyd and Crang from Teenage Mutant Ninja Turtle did acid together..." lostchild14000

"Yay, a space octopus! With– wait, what? He has amnesia? Oh bother. Poor thing. That’s going to be troublesome for his exploratory mission, in search of new worlds, and so on. Or in this case, already well-known worlds, since he’s limited to whatever is in the game. A game which, for all intents and purposes, looks rather trippy. I mean, really, an octopus in space, with amnesia no less, “quirky characters”, and… well, have you seen the trailer below? That’s one crazy universe; crazy and potentially awesome!" Wraithkal

"I'm amazed <3 Visuals effects are unbelivable..." Rémi Alves

"A marvel. An initiatory journey." Constance Henrot-Tardivier

"Beautiful images, a breathtaking soundtrack, a world like no other... but fuck it's not easy!" Eva Quéméré
