Independent games

Fly the curve

Small games about real things (gravity, orbits, momentum) that teach you something true while you play. Built by Jeffrey Stone.

The developer

One person, physical games, no fine print

I make focused iOS games where the physics is the point rather than a backdrop. The current one puts you in the gravity well of a black hole and asks you to think in orbits. More titles are on the way, all built on the same idea: real mechanics, faithfully simulated, fun to feel.

Learn something true

The games come with the science attached

Everything in the duel is real physics, and the game became the platform for a small research lab. Both stories are written up here, at whatever depth you're curious about.

The orbit lab

Think in orbits

Gravity's user manual: no equations, three toys you can fly. Why falling is flying, why the brakes make you faster, and how to bend a shot around a black hole.

The lab notebooks

Two tiny neural networks

One taught itself to fly the ship, and to cheat. One watches the screen and paints everything it recognizes. Real experiments, real failures, with the films.

The flagship

iOS Beta

Spacewar: Orbital Duel. Battle at the singularity.

There's no flat space here. A black hole sits at the center and pulls on everything: you, your opponent, and every shot fired. Good pilots think in orbits: ride them, bend shots around the well, treat the singularity as a weapon. Ten minutes in the orbit lab and you'll fly like you mean it.
