Version 1.4 is live!

After two days of trials and testing, the last patch is completed.

The main changes aim to make the blue quads resource scarce.

Before this change, the blue quads were abundant from level 15 onward, which made the game feel too easy. It also allowed to buy plenty of hp modules.

The amount of quads dropped has been reduced so that, after every level, the player has just enough to fill the blanks in his build.

The price of the hp module has also been greatly increased. Choosing to buy an hp module instead of an offensive one now feels like a big sacrifice.

The option to farm previous levels remains for the players that have trouble and I made sure that it is still possible to beat the game by playing every level only once.

“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 [...]”

“Ottropi Games has found a fun and inventive way to stand out from the glut of dual-stick shooters. That is why Cuboid Keeper is not to be missed.”

About This Game

Cuboid Keeper is a 2D arena shooter with ship building elements and a captivating 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 waking up, the hero 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 make 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 captivating story about four advanced, but flawed, civilizations and an ancient secret giving hope to the entire galaxy.
