DESKTOP ONLY, FOR NOW
We are currently working on a mobile experience. Stay tuned.
You are the smallest, ugliest rock in a young solar system. You have five minutes to make yourself capable of supporting life — by ramming, robbing and generally ruining everyone else's orbit.
Or drive it: the stick bottom right pushes the same three axes — up and down for speed, side to side for orbit, diagonals for both — and the two arcade buttons spin you up and down. Tap one for a step, hold it to wind.
On the speedometer, the white needle is where you are and the amber one is where you asked to be. The gap between them is the game. The inner green arc is the temperate band: park there.
Mass, water, atmosphere, temperature and damage, all satisfied at the same time, held for ten seconds. The pills across the top go green as you get there.
HIT rocks for mass. Anything much wider than you cannot be
swallowed — you bounce off it and take the damage.
MATCH a planet's speed and pull alongside without touching it, and
you siphon its ocean.
RIDE a gas cloud for atmosphere.
PARK in the green band to get your temperature right.
SPIN to knit your craters shut — faster heals faster, but past
the green mark your orbit starts shaking itself apart.
Everything orbits the same way, so you may only speed up or slow down, never reverse. The star is always on your right.
Inside the red ring the star boils off your water and air — but it also welds your wounds shut faster than anything else can.
The red dashes on the speedometer are where a hit stops shoving a planet and starts breaking it in half. You have to be genuinely flying to reach them.
Loiter beside a planet without hitting it and you can peel off its moons. Each one is eight seconds off your final time.
A Hole Planet is a five-minute orbital game about creating life by being an absolute menace to the solar system.
You drive a planet like a car — changing its orbit, managing speed and spin, and using momentum to navigate a living solar system. Steal water from neighboring planets. Rip away their moons. Plow through asteroids for mass. Skim gas clouds for atmosphere. Ram smaller planets hard enough to break them apart. Then somehow park the wreckage in the habitable zone and create life.
The objective is wholesome. The method is not.
That contradiction became the foundation for everything: a cinematic, almost-serious space simulation where the player is very clearly the problem.
Built from scratch in TypeScript and Three.js, without a game engine.
At its core is a deterministic 2D polar simulation completely separated from rendering and the DOM. The entire game can run headlessly at a fixed timestep, while Three.js acts as a view onto that single simulation state.
The visual systems are driven by the simulation rather than authored as predetermined states. Damage physically carves craters into the planet. Water collects inside that changing terrain as oceans form. Atmosphere expands around the planet as it accumulates. And when a planet is destroyed, its sphere separates into geometric wedges that still perfectly reconstruct the original body at the instant it breaks apart.
