Metric Relay is a puzzle game inspired by the concept of metric dimension from graph theory, which felt like a good fit for this jam.

In each sector, you place a small number of beacons on relays so that every relay in the network can be identified by their unique transmission delays (*shortest path distance*) to those beacons. No two relays should share the same delay pattern.

Groups of relays that share the same delays to the placed beacons are considered ambiguous and are highlighted with a specific group color and effect for clarity, while relays with unique delay patterns remain blue.

The game tells this through the story of a collapsing communication system that must be restored sector by sector. There are 120 levels, starting simple and gradually becoming more challenging, as the relay networks grow larger and more intricate over time.

How to play


The game is mainly designed to be played with a mouse or touch screen.
You place or remove beacons by clicking or tapping relays.
You can zoom in and out of the sector, which is useful on later maps.

While the game is embedded here, my spaghetti code does not handle full-screen yet.
Moreover, Ludum Dare embedding does not allow saves.
For a better experience, I advise you to play the game on itch.io with the link below.
