Beam Time

Beam time is a logic puzzle game where you redirect and split laser beams to create digital circuits. Through the campaign, you will explore logic gates, oscillators, latches, counters, adders, memory, and more.

Each level provides a description and some test cases your solution must pass. Inputs are passed in through laser emitters and outputs taken from beam detectors. It's your job to use some combination of components to complete the level.

Here are all seven in-game components from left to right: emitter, galvo, splitter, mirror, delay, wall, detector. Galvos are the only 'active' component, they rotate the mirror they are facing when powered. With just these few components, It's theoretically possible to perform any computation.

The game also features a sandbox mode where you can build whatever you want. Below is a zoomed in view of an implementation of the one-dimensional elementary cellular automaton Rule 30.
