Version 1.2 is live!

The difficulty of all the bosses has been reduced in easy mode, by removing some attacks, making them slower, and/or decreasing their hp. The hard difficulty remains the true challenge for hardcore gamers!

“On top of solid shooting action and enemy patterns that reminded me a bit of a 360-degree Galaga and a soundtrack inspired in part by classic techno – complete with rave whistle – Cuboid Keeper also features an intriguing, high concept sci-fi narrative a la Arthur C. Clarke”

About This Game

Cuboid Keeper is a 2D arena shooter with ship building elements and a complex story.

The game consists of about 40 levels. Each level takes place in an enclosed play zone where the player must fire on the enemies that successively spawn, while evading their attacks by transforming into a Spark.

Between each level, the main character can be rebuilt by assembling modules. Each module enables a skill that complements the others and requires adapting the play style to fully master. Modules can be equipped many times to increase their effect.


A few seconds after being born, the player receives his mission from four shady overseers: he is the Guardian of the Cube and must destroy all the intruders without mercy. So begins the legendary challenge, clashing four lost and hopeful civilizations against a devoted but confused Guardian. Does any of this makes sense?


  • Solid controls (twin stick style), easy to learn, but hard to master.
  • Ability to play with keyboard only, keyboard + mouse or controller.
  • A constantly evolving ship: it grows after each level and new modules are regularly unblocked, forcing the player to adapt his playstyle.
  • 40 hand made levels, with 8 mini bosses and 8 bosses.
  • A strong story about four advanced, but flawed, civilizations and an ancient secret giving hope to the entire galaxy.
