It's billiards, except the balls are planets and gravity matters.
Wishlist on Steam — coming soon
The solar system is your table. The planets are your balls. Gravity plays for both
sides. Reach in with your own two hands, flick a world, and watch the consequences
ripple through the whole system: mergers, splits, slingshots, and the occasional
spectacular catastrophe you will absolutely claim was the plan.
What you do
One verb, repeated: pick a body, flick it, and let gravity resolve the
consequences.
Pick a world
Fly through the system while time runs fast-forward and the orbits visibly
evolve, or hand the camera to the cinematic director and let it find the shot.
Click any body you're allowed to touch to lock on.
Aim the flick
Your hand closes around the locked world. Pull back to charge, read the
trajectory preview, and release. The same flick nudges a star imperceptibly and
hurls a moon clean across the system.
Let gravity resolve
Every body pulls on every other, deterministically. Two worlds that meet gently
merge. A hard glancing hit shatters the smaller one into hot rubble that cools,
settles, and sometimes rains down on its neighbours.
Play billiards with planets
Cosmic Billiards is the campaign: 60 authored levels across 13
chapters, each a small system with an objective sheet and no shot limit. Every puzzle
is authored, every solution earned, and when three bodies conspire to do something
nobody predicted, that's not a bug. That's the three-body problem. It's famous.
Merge, split, sink — pocket a rock into a black hole, feed a hungry
star its rogue, or crack a gas giant into a spray of fragments and keep only the
pieces you need.
Orbits are objects — later chapters ask for a shape, not a body
count: park a world in a resonance, thread a gate, hold a formation, build a
shepherd's fence.
The Long Throw — escape one star system, coast across the dark,
and get captured into a stable orbit around another.
The Hard Rain — aim one cause and read many effects. Skim a moon,
start a chain reaction that shatters a whole system, and keep the one world that has
to survive out of the rain.
Records — every level counts your impulses. Fewest wins, per
difficulty tier, with Steam achievements and per-level leaderboards.
And there's more
Three more ways to play with an entire solar system. Same physics, same hands,
very different jobs.
Cosmic Survival
Start as a mote of matter and eat your way up. Every tap of thrust costs mass,
every smaller body you touch is lunch, and anything larger is trying to eat you
back. Win, and you're no longer in the solar system. You are the solar system.
Cosmic Evolution in development
A roguelite lifecycle. Begin as a microbe in a pool, scan for what's smaller than
you, harvest minerals, and grow organs through the evolution web. Launch off your
planet, leave your home system, and end as a black hole of your own making.
Seeded runs, a genome archive, and a death card that tells you exactly what got
you.
Idle Universe
Stop playing and just watch. A living orrery where an autonomous civilization
grows from steam and steel to satellites, probes, asteroid mines, and a Dyson
swarm, then launches an ark for another star. Follow a craft, pick the song, or
arm the flick and change their fate.
Under the hood
Your own hands — the camera is your eyes and a pair of hands
reaches into the system to cup, push, and flick. Lock on and a hand closes around
the world; strike and it lets go.
A broadcast director — press C and the camera directs
itself like a live sports feed: it scores what's interesting, frames it, holds the
shot, and cuts when something better happens. Your input keeps working the whole
time.
Real N-body physics, tuned for play — every body pulls on every
other, every collision is resolved into a merge, a deflection, or a split, and the
result is deterministic. Replays are exact: the same inputs produce the same
universe.
Generated, not loaded — worlds, debris, effects, and the adaptive
soundtrack are all synthesized in code; the few 3D characters are baked into the
executable. Nothing streams in loose from disk.
Play it your way — keyboard and mouse, gamepad, or touch.
Adjustable difficulty, and the physics stays honest at every tier. Accessibility
options throughout: subtitles, colour alternatives, contrast and text-size controls,
keyboard-only or mouse-only play, adjustable pacing, and camera-comfort settings.

Twin Worlds — lock on, and your hand closes around the world you're about to flick.The Hard Rain — one skimmed moon, seven links deep. The cinematic director rides the debris front.Corner Pocket — roll the rock into the black hole's mouth: slow and close, or it slingshots past.Clockwork Orrery — merge each cog with its colour twin, and spare the odd one out.First Contact — throw a world across the dark to a second star and let its giant brake you into orbit.
