Idlenaut

Idlenaut is a single-player incremental space-industry game played in real time across a top-down 2D procedurally generated star system. You grow an economy across the planets, and every part of that economy is visibly simulated. Cargo ships fly their routes, extraction ships haul space rock and particles home, and a Dyson swarm assembles around the star one sail at a time.

Industry
Set up per-planet production chains: miners harvest raw ores, refiners create refined materials, and fabricators produce goods like copper wire, rocket fuel, battery cells and solar sails.

Everything you produce pays out as it is made.

Power comes from solar, wind, coal, steam, nuclear and orbital solar plants. Each planet has its own sunlight and wind environment.

Build observatories, research stations, gold reserve banks, battery arrays, maintenance stations, rock crushers and solar sail launchers.

Ships that actually fly
Transport ships run multi-stop cargo routes between your planets.

Extraction ships harvest moons, asteroid belts and nebula anomalies, hauling rocks and particles home for crushing and research respectively.

Discovery ships survey the system while observatories push back the fog of war.

Every ship flies a curved orbital path, climbing away from its planet, steering around the star, and braking at its destination.
The Dyson swarm
Fabricate solar sails and launch them into rings around the star, row by row.

Sails fire orbital rays at facing planets, feeding orbital solar plants and orbital ray repeaters.

Sails have limited lifetimes, requiring launchers to be kept fed.

Threats
Enemy carriers arrive in waves, deploying invaders that latch onto planets to choke output.

Space Force centers field fleets of three fighter marks armed with lasers, ion weapons, guided missiles and quantum beams.

Fighters hunt, dogfight, disengage and regroup automatically without direct piloting.

An adaptive director paces events to your economy, triggering hazards like ion storms or windfalls like mineral blooms.
Ascend
Unlock over 100 research nodes across mining, refining, fabrication, energy and structures.

A quantum particle accelerator collides antimatter and neutralino samples into quantum credits to buy permanent upgrades.

Ascend to start over in a new procedurally generated star system while keeping quantum upgrades.

Systems feature shaded stars, rocky and terrestrial worlds, gas and ice giants with moons, asteroid belts and glowing nebula anomalies.
