FLOWFALL Inertia is one long fall through a universe of neon, music and motion.

You look down a long, winding shaft. Gates rise toward you, each cut with a shape: circle, cross, square or line. Steer onto the hole and morph your piece to match before you cross. Thread it perfectly and the world flares with light. Chain clean passes to build FLOW: the fall speeds up, the colours shift and your score climbs.

A meditative fall with room to show off

• Small mistakes are forgiven. Graze an edge and you keep going.

• Big mistakes cost health, and your health shows on the piece itself as its glow fades. Run out and it shatters.

• Health pickups keep you going. Corridors tempt you off the main line for bonus points. Power-ups let you phase through an obstacle, shrug off a shock or ride a slipstream. GUIDE lights your best path through the next gates, and AUTOPILOT carries you safely through the next one.

• Mastery makes the fall faster, brighter and more spectacular.

Every fall bends and splits

The shaft curves and winds through every world, and then it splits. At a fork the tube opens into two to four routes, left, right, up or down, each with its own gates and hazards. Take the long way round or gamble on a shortcut. In the Quantum realm the routes twist around each other like strands of light.

MULTI-FLOW: fall together

Two to four players online, with cross-play between PC and Android.

• FLOW RACE: everyone drops into the same fresh course. Race each other's glowing pieces, name plates and all, to the finish.

• DERBY: an endless shared descent where pieces shove each other into the walls. Grab SPIKES, SHIELD, SHOCKWAVE, BEAT MINE and a homing shot that hunts the player ahead of you, and smash through hazards on your way down. The last one falling wins.

• Race the top ghost: fly a level against the recorded run of its leaderboard champion.

• Shattered early? Watch your rivals fall, then call for a rematch.

One fall, endless worlds

Leave the Void and fall through Deep Space, Orbit, Atmosphere, Forest, The Machine, the Reactor, the Frozen Complex, Underwater, Magma Fissure, Hollow Earth, Quantum, Synthwave, the Microbiome and, at last, a living Biosystem. Every world has its own hazards: asteroids and alien tractor beams, planes and bird flocks, grinding gears, a reactor meltdown, ice that locks your shape, lava falls, a black hole's pull, and white blood cells that hunt you down.

Every gate is timed to the music

An original soundtrack by ComAdore drives everything. Gates land on the big moments, and the light breathes with every beat. The ring around your piece ripples with the kick and the snare, so you can feel the beat before the gate arrives.

Many ways to fall

• Story: hand-built courses, one for each song, with stars, three difficulties and a story told between the worlds.

• Arcade: an endless climb that gets deeper and faster over ten minutes, mixing worlds and mechanics in every stage.

• Daily Drop: one new course a day, the same for everyone, with its own leaderboard.

• Custom courses: pick the world, song, gates, hazards and difficulty, then challenge your friends on your creation.

• Import your own songs: the game builds a unique course from your music.

• Online leaderboards for every level, difficulty and mode, with every score checked by the server.
