Spatial Quotient Interactive presents
One long fall through a universe of neon, music and motion. Steer your glowing piece, change its shape and slip through gates timed to an original soundtrack.
Free demo: play in your browser or on Steam
Simple to begin. Room to shine.
Gates rise toward you up the winding shaft, each cut with a shape. Steer onto the opening, morph your piece to match and slip through on the beat. Clean passes build FLOW: your score climbs, the colours shift and the fall gathers speed.
Small mistakes are forgiven: graze an edge and you keep going. A harder hit dims your piece's glow, because your health lives on the piece itself. Gather a little health, settle back into the music and take the next opening.
Launch trailer
Drop into the same shaft as your friends, or anyone online. Everyone sees everyone: glowing rivals with their name plates, flying the same gates to the same song.
From the vast to the living
Leave the Void for deep space. Fall through sky and forest, machinery and ice, ocean and molten rock, toward a singularity, into neon and finally inside a living world. Each place brings its own song, atmosphere and hazards.

The first breath. Learn to steer, change shape and read the red approach outline before the journey begins.
World guide →
Asteroids crumble, comets fling you along their path and an alien tractor beam pulls you toward its hull.
World guide →
Beeping satellites sweep the shaft and break apart, while heat builds as the planet pulls you in.
World guide →
Burn through reentry into open sky: planes, bird flocks and hot air balloons share the way down.
World guide →
Bending branches, waterfalls that soak you, spider webs and fireflies under the canopy.
World guide →
Thread the turning gear's gap, dodge pistons and lasers, and match the key gate before the door seals.
World guide →
Thread the core's eye before it blows. Then live cables, arcs and a wall of fire chase you down.
World guide →
Ice shelves, falling shards and blizzards. Keep morphing, or frost locks your shape.
World guide →
Steer against the current as fish schools part around you, jellyfish sting and a whale glides by.
World guide →
Lava falls burn while you linger, rivers span the shaft and vents erupt through the walls.
World guide →
Floating islands drift past as the gravity of a black hole pulls you toward the centre.
World guide →
Phase rings let you slip through; fields of uncertainty numb your steering. Echoes of earlier worlds flicker past.
World guide →
Pulse grids switch on the beat and slipstream pads launch you forward through the neon.
World guide →
Germs, mucus curtains, wall colonies and a tardigrade that bounces you on your way.
World guide →
Ride the bloodstream past white blood cells and heart valves that open on the beat, toward the journey's end.
World guide →A fall for every mood
A hand-built course for each song, with a story told between the worlds. Earn up to three stars on Easy, Normal or Hard.
An endless shuffle of the whole soundtrack. Every song is a new stage and a new world, and DEPTH slowly turns up the pressure.
One new course every day, the same for everyone, with its own leaderboard and a countdown to the next.
Pick the world, song, gates and hazards, or bring your own music file and let the game time the gates to it.
Online boards for every level, difficulty and mode, with every score checked by the server. Show off your name plate.
Keyboard, mouse, controller, touch or Steam Deck, all rebindable, with vibration, captions, colour-vision palettes, larger UI, reduced motion and reduced flashes.
Forks split the shaft into two to four tubes, left, right, up or down. Each has its own gates and hazards; one might be a shortcut. In the Quantum realm the routes twist around each other like strands of light.
Original soundtrack by ComAdore
Gates land on the big moments of each song, and the light breathes with every beat. The ring around your piece ripples with the kick and the snare, so you feel the beat before the gate arrives. On Steam, the complete soundtrack comes free with the game to download and enjoy anywhere.
