Solar Stride

Ten worlds, each with its own gravity, light, and live-generated music. Bank your distance through the hoops — or lose it to the chasms.

Ten worlds. One runner. No two songs ever the same.

Solar Stride is an endless runner across the solar system — the Moon, Mars, Venus, Earth, Mercury, Pluto, and out to the far moons: Europa, Io, Titan, Triton. Every world has its own gravity, its own terrain, its own light, and its own music.

EVERY WORLD RUNS DIFFERENT Lunar gravity floats you over craters; Venus drags you down through crystal highlands; Titan's dunes roll on forever under orange haze. Jump the chasms, smash through the rocks (your suit can take four — barely), and watch the sun cross the sky: every planet runs a full day-night cycle while you explore, and the world changes with the light.

BANK IT OR LOSE IT Progress isn't given — it's carried. Run your distance through the giant glowing checkpoint hoops to bank it. Fall in a chasm first, and everything since your last hoop is gone. Distance you bank builds your lifetime record, and your lifetime record unlocks new bodies, new suit colors — and at 100 km, the Surge Belt: infinite jetpack, forever.

SOMETHING IS FOLLOWING YOU A visitor makes its rounds. When the beam comes down, the music turns with it — jump, burn fuel, or turn and fire. The ray gun never runs out.

MUSIC PERFORMED LIVE, IN THE MOMENT Nothing here is a recording. Every world has its own songbook — motorik on Mars, bossa nova on Venus, dub on Pluto — played live by a generative music engine with real music theory under the hood: modal harmony, walking bass, improvised solos with actual phrasing. Every performance is one-of-one. You'll never hear it again.
