A psychedelic rhythm-infused action platformer

Octahedron is a vertical action game about creating your own platforms.

Ascend and escape strange subterranean world Veetragoul, and experience an otherworldly psychedelic adventure. To conquer and master each of the handcrafted levels, you must get into the flow of the pumping, atmospheric soundtrack, as enemies and traps move along with the rhythm.

Discover new obstacles, adversaries and mechanics in every level, with clever gameplay that is easy to learn but difficult to master. Unlock powerful offensive abilities for your platform and fight back against Veetragoul’s peculiar foes. 

Octahedron released in March 2018 on PC, Xbox One and PS4, and in January 2019 on Nintendo Switch. It was published by Square Enix, one of the biggest video game developers and publishers in the world.



Octahedron is a solo project I developed over the course of 4 to 5 years. My work consisted of:

  • Game Design

  • Programming

  • Visual Design

  • Story

  • Sound Design

  • Music

  • Localization

  • Porting to 4 different platforms

  • Social Media & Marketing

​The game's soundtrack is a collaboration between several different artists (including myself under the alias Monomirror). Sound effects were designed together with Jordan Fehr.

For publishing and platform holder relations I founded Demimonde GmbH, a game development studio holding the rights to the game.
