Launch Window is a single player physics-based automation game where you establish supply chains across an entire solar system using Newtonian orbital mechanics. Transport resources and populations between colonies using real physics. Build infrastructure to construct more ships. Use those ships to establish new supply routes. This is how the colony grows.

Your first launch may carry a handful of colonists and supplies to a barren moon, founding your first extra-planetary outpost. Years later, you command a fleet of hundreds of ships traversing the solar system, each one following a trajectory you planned, bound for a sprawling colony you designed.

• Start with a lone planetary outpost, and develop into a full solar system-wide colony

• Coordinate fleets of 1,000+ Newtonian physics-based spaceships

• Automate orbital shipping lanes, plotting routes rather than individual burns

• Build across entire spherical worlds, placing structures anywhere on a planet's surface

• Craft logistical networks on-surface and between different planetary bodies

• Research and unlock more advanced technology, manoeuvres, and buildings to improve your colony and extend your reach

As you are in command of up to 1,000+ ships simultaneously, you are not required to calculate every inter-planetary manoeuvre yourself. Instead, use physics to plot and execute orbital manoeuvres, setting up automated shipping lanes to transport resources between celestial bodies.

All manoeuvres happen on a single plane, meaning you can read your solar system at a glance, tracking hundreds of trajectories without losing the thread.

As there are only certain times reaching different planetary bodies is possible (the Launch Window ), you will have to plan carefully what resources are needed at which colonies, how long they will take to get there, how long they will take to be resupplied. This logistical puzzle is the basis of the game.

You have full rein to build across the entire surface on each planet you inhabit. Build solar panels to extract sunlight, build drills to extract resources, and build factories to amass your fleet. The reach of the colony depends on the infrastructure that feeds it.

Each planetary body offers different resources and challenges. Ice-rich moons provide water for fuel production. Metal-rich rocky bodies feed your factories. Outer planets offer rare resources but longer transit times. Where you expand, and in what order, shapes the logistics of everything that follows.

Once you have planned your trajectory, built your spaceships, and filled them with cargo, it's time to light the candle. Launch from your pads when the windows align. Timing is everything.

Use flagships to lead your convoys across the system, not worrying about each-and-every ship. This game's been built for optimisation and consistency, so even at very high time warp (up to 100,000x) your fleet and their physics operate reliably and with high performance.

EARLY ACCESS

Launch Window is in active development. The core game mechanics - orbital physics, automation systems, and planetary production will be playable on early access release. Your feedback will directly shape what comes next as the solar system expands.

Major planned features include:

• Terraforming (atmosphere/water/temperature)

• Asteroid/comet redirection and mining

• Celestial dangers (e.g., solar flares)

• Megastructures, both orbital and terrestrial 

Also expect regular updates adding new technology, buildings, ships, and more.

ABOUT THE STUDIO

gumptiongames consists of 1 dev, Fred (that's me, hello). Motivated through a love of sci-fi, physics sims, and space in general, I want to create games that capture the vastness of space, have satisfying orbital mechanics, and give the joy of expanding logistics networks. My hope is to bring this ideal to life through Launch Window, and I am eager for thoughts and feedback. Please do get in touch!
