ENDLESS
The classic. Run as far as you can. Speed ramps from 220 to 680 points/sec over 55 seconds, then doesn't stop. Most players spend their first 10 hours here learning the dimension shifts before tackling Daily.
Shift between three color dimensions
● cyan
■ magenta
▲ yellow
The shift is the verb. Color is the puzzle. Off-color obstacles fade and can't hurt you. Off-color crystals fade and can't be collected. Every shift asks the same question: which color dodges this hazard and collects those crystals?

The world scrolls forward. Hold the left half of the screen to climb against gravity. Tap the right half to phase from cyan to magenta to yellow and back. Crystals and obstacles only interact in your active dimension — everything else fades to non-lethal, non-collectible.
The shift is the verb.
Color is the puzzle.

One mechanic. Five different runs. Endless score chase, a daily challenge that's the same world for every player worldwide, a timed run where the multiplier escalates as the clock drops, no-fail Zen, and Practice that starts you at any score you choose.
The classic. Run as far as you can. Speed ramps from 220 to 680 points/sec over 55 seconds, then doesn't stop. Most players spend their first 10 hours here learning the dimension shifts before tackling Daily.
Seeded biome and obstacle layout — your run and your friend's run hit identical walls. Records a Ghost Run of your best attempt to race tomorrow.
1× through to a minute left. Then 2× → 3× → 5× as the clock crosses 60s, 30s, 10s. Last ten seconds are where runs are won.
No deaths. Collisions bump you instead of ending the run. Designed for music, biomes, and flow — not score. Pair it with the Cherry Blossom or Kelp Forest biome and lose half an hour without noticing.
Pick a starting score and dive into the speed. The fastest way to rehearse what late-game feels like without grinding the early game. Speedrunners use this to learn boss patterns; everyone else uses it to figure out why they keep dying at 12k.
The world cycles biomes every 22 seconds. Each owns its own gradient sky, soundtrack layer, and signature hazard. Long sessions feel like a tour of impossible places — not the same arena on repeat. Nine free biomes ship in the rotation; three more come with Pro Edition.
Hazard: meteors
"Ethereal synth wash, distant wind-chime tinkles, deep space."
Cosmic violet starfield, distant nebulae blooming. Meteors arc across the lane behind a crosshair telegraph — read the trajectory, then fly clear of the line. The calm opening act.
Hazard: falling stalactites
"Echoing dulcimer plucks, glass percussion."
Cold cyan vaults, ceiling glittering. Crystal stalactites sink from the ceiling behind a ghost-preview telegraph — the lower lane stays safe. Echoing dulcimer plucks. Stay low.
Hazard: laser beams
"Vintage synthwave arpeggio, gated reverb snare."
An 80s retro horizon: chrome, glow, vapor. Lasers lock onto your altitude with a dashed-line telegraph, then sweep — climb or drop, fast. Vintage synthwave with gated reverb snare. Pure cyber.
Hazard: lightning columns
"Heavy industrial drone, distant thunder, ominous bass swells."
Slate purple under cracking sky. Lightning columns strike from the top or bottom edge after a flickering telegraph — when it strobes, clear out. Heavy industrial drone, distant thunder. Endurance world.
Hazard: solar flares
"Floating choir pad, wordless soprano, vibraphone tinkles."
Green-cyan auroras drape deep space. Solar flares ignite right where you fly and expand into a lethal ring — keep moving. Floating choir pad, wordless soprano. The ethereal one.
Hazard: fireballs
"Crackling fire ambient, deep brass swells, distant bell tolls."
Sunset gold and orange, the air on fire. Fireballs streak in at your altitude after a pulsing telegraph. Crackling fire ambient, deep brass, distant bell tolls. Heat and weight.
Hazard: firefly swarms
"Soft acoustic-guitar harmonics, wooden flute trills, dappled sun."
Dappled light through leaf-green canopy. Firefly swarms drift across the lane in a glowing cluster — beautiful, and lethal to touch. Soft acoustic-guitar harmonics, wooden flute, birds. The on-ramp.
Hazard: petal vortex
"Koto plucks, shakuhachi flute hints, zen meditation."
Sakura pink under a pearl sky. A petal vortex blooms in your path — the swirling petals are harmless; the flower at its core is not. Koto plucks and shakuhachi hints. Meditative — Zen mode lives spiritually here.
Hazard: kelp whips
"Underwater pad, swaying current, whale-song bass swells."
Teal and sea-green; the world tilts underwater. Kelp strands whip up from the seafloor — a ghost outline traces each one before it turns lethal. Underwater pad, swaying current, whale-song bass. Slow and dense.
Hazard: hologram billboards
"Neo-Tokyo synthwave, rain ambience, neon FM bell stabs."
Hot pink and electric cyan neon city, drowned in rain. Glitching hologram billboards sweep the lane as full-height walls with a single gap — find it and thread it. Neo-Tokyo synthwave with rain ambience. The most kinetic Pro world.
Hazard: anglerfish snap
"Bioluminescent ambient, glassy mallets, sonar blips."
Bioluminescent green and jellyfish purple. An anglerfish lure drifts into your column and pulses three times — move before the jaws snap shut. Glassy mallets, sonar blips. Pro Edition's most painterly biome.
Hazard: dragon breath
"Cinematic golden warmth, taiko drums, mystical Eastern."
Molten orange and gold, cavern lava and cinematic warmth. A dragon rears in from the right edge and exhales a cone of flame — escape the wedge before it ignites. Taiko drums, mystical Eastern brass. The final world.
Daily Challenge pulls from all 12 biomes (free + Pro), so non-Pro players get a taste of the premium worlds about once a week.
Collect four crystals of one color and that color's power triggers automatically. Powers are your reward for committing to a dimension. Boosts are rarer — chaos crates that drop into the field at score milestones, each one a different way to play.
4× CYAN
Doubles scroll speed for 5s. Risk-reward — covers more ground but obstacles arrive faster.
4× MAGENTA
Pure invulnerability for 6s. Phase through anything in any dimension, no questions asked.
4× YELLOW
Pulls all crystals within a 220pt radius for 7s. Built for combo extension, not panic.
Each unlocks at a score milestone, can be bought outright with crystals, or comes free with Pro Edition. Treat them as ways to play, not as power-ups.
Go invisible. Phase through every obstacle for 8s.
Unlock at 250 · or 250 crystals
Extra life. Absorbs one hit and shatters the obstacle, then ends. Lasts up to 12s.
Unlock at 1,000 · or 500 crystals
Slow time. Crystals score 2× for 7s.
Unlock at 4,000 · or 800 crystals
Screen-clearing detonation. Shatters every obstacle on screen and keeps clearing new ones in front of you for 10s.
Unlock at 10,000 · or 1,500 crystals
Pro doesn't change the leaderboards. Game mechanics, scoring rules, and achievements are identical for free and Pro players. Pro adds worlds, not power.
Get Pro on App StoreFive recurring engagement loops, all on by default — no subscriptions, no event timers, no FOMO. Just calendar-driven texture so the game changes shape across the week.
Three fresh quests every UTC day, identical for every player worldwide. Collect cyan crystals, hit a score, complete the daily — finish all three and your shards land automatically.
Every Saturday and Sunday: 1.5× crystal score, all weekend long. The best window to grind out a new skin or trail.
The 14th of every month: Magnet on for the entire run. The day to chase wild crystal counts and Hoarder-tier achievements.
Daily Challenge records a phantom of your best attempt. Tomorrow's same seed comes with that ghost on the track — race yourself, frame for frame, until you beat it.
Open the app on consecutive days to build a streak. Each new day pops a reward toast — shards, occasional bonus crystals — and the streak count rides iCloud across your devices.
Save data, cosmetic selections, unlock state, and crystal balance sync via iCloud — score on your iPhone, brag on your iPad. Game Center handles sign-in, leaderboards, and achievements. App Clip support is queued for a v2.x update — try the core mechanic in 30 seconds without installing anything.
