About Criterion

Criterion - about the game

Criterion is a space optimisation puzzle game about designing efficient solutions under constraint. Process the color fluxes. Control their strength. Solve increasingly complex networks where every tile matters. 

There is always a solution, the question is how elegant yours will be.

Each color source must be connected to its matching sink. As new colors unlock, systems grow denser.

Fluxes must be mixed and routed with precision, creating new possibilities and deeper system interactions.

How elegant can you make it?

Use processors to increase or decrease flux strength to reach exact targets. But the grid is finite.

Every block competes for space, every move affects the system, every inefficiency impacts your final score.

Optimisation is not optional.

Discover a main story through 54 levels and uncover the purpose of the systems you are building.

Will you be able to solve all the Systems? 

Criterion sits between logic puzzles and factory optimisation and scratches that itch for elegant solution design with:

  • Tight spatial constraints

  • Clean minimal systems

  • Exact numerical balancing

  • That moment when everything clicks

Key features
  • Optimise systems like never before, play with constraints and the limits of your brain.

  • Master 54 main story levels at launch

  • Responsive soundtrack by Hi5 Music that intensifies as the system grows

  • Retro-futuristic minimalist aesthetic

  • Night mode & colorblind accessibility

  • The phenomenal feeling of solving systems like an engineer would
