Aster Symphona

Aster Symphona is a factory automation game where you produce materials and, as a result, create beats and music. You set miners to gather minerals, process them through nearly 80 recipes and arrange production buildings whose sounds and timings combine in different ways.

Automate production

You mine six types of minerals, smelt their ores into ingots, then roll, press and assemble materials. Buildings use different pieces as inputs, so a recipe is determined by the order and placement of materials rather than by selecting it separately. Each recipe has its own sound and timing, allowing for many combinations.

Move materials

Belts carry materials between buildings and factories across asteroids. Short-range teleporters move them through buildings, while trains ship products over long distances and between asteroids.

Solve each level

Every level is a self-contained puzzle: deposit the requested materials at the hub to complete it. Mistakes and imperfections in one factory do not affect later levels, so you can design each one your own way. Recipe ratios matter, but ignoring them can create a sound unique to your playthrough. Levels test spatial problem-solving and call for compact factory designs, with the challenge increasing as you complete more of them.
