TAP
Change lane. One lane per tap, outward, and it wraps at the edge.
A ONE THUMB ARCADE RUNNER
Run a stone ring that never ends, with a growing line of odd little creatures behind you.
A STORY ABOUT LIFE AND REBIRTH
You run on a track that never ends. You eat what you can, you dodge what you must, and in the end you die. Then the loop starts again. Kai's name comes from three Japanese words that all sound like kai: 回, to go around; 甲斐, to be worth it; 開, to open. He goes around and around. Every lap is worth it. Every death opens the next one.

A small pilgrim in a stone mask half as tall as he is. The mask cracked long ago and healed that way. His two horns are his lives. Hit something and one horn breaks. Hit something with no horns left and you lose your head. A broken horn grows back, but not as bone: it is made of the stage you are in. He runs with his head down and rams whatever is in the way.
TWO MOVES
The longer the line behind you, the more it pays when you set them free.

Change lane. One lane per tap, outward, and it wraps at the edge.

Dash forward and free the creatures you carry. The dash breaks what it hits, and every barrier it breaks pays.

Zoom the camera in or out. Two fingers, during a run. The game keeps your distance.

Zoom the camera in or out. Mouse wheel, or drag with the right button. L2 and R2 on a controller. The game keeps your distance.
SIX WORLDS
Five of the six stages are dark, each lit by one thing. The Moss Ring: an island around a tall crystal. The Pale Tide: pale sand under cold water. The Spore Hollow: mushrooms and drifting spores in the dark. The Magma Field: cracked black rock and glowing melt. The Spine: a road made of bone. The sixth is different. After bone there is nothing left, so The Tear is bright, and it is the bottom of the world. The roads from the stages above fall down as rain, and the five monuments lie broken on an island of glass.






YOU ARE NOT ALONE
This world is a terrarium, and something outside is looking in. A face comes up out of the dark. A hand comes down to block the road. At the bottom of the world the face never appears. Only the hand.



THE COLLECTION
More than fifty strange species, and a different mix every game. They follow Kai in a line, in the order you ate them. Let them go and they spiral up around the monument and leave the world. Every hundred you free grows one horn back.
Every oddity you meet is kept for good. Find them all to unlock three secret horns.
HOW TO PLAY

Each creature adds its value × your multiplier × 3 to the hoard. You carry ten at most.

1 + 0.5 per tier. Tiers come from eating. Double or a boost pad doubles it.

Pays the hoard × a run bonus that climbs the longer the run burns, up to ×3.6.

Costs 4% of your score, half the hoard and a horn. No horn left, the head comes off.

Buys a horn back.

Red. A hit costs a horn, or your head. Dash through it and it pays.

Stage 3. Slides between lanes. An X marks the lane it blocks, a ring the way past.

Never kills. Shoves you back, empties the hoard and takes 2% of your score. A dash breaks it.

A finger comes down and blocks lanes. An X marks the blocked lane, a ring the way past. It thinks first, then strikes.

Stage 4. The lava bubbles, then throws a glob onto a marked lane. Where it lands, a pillar of fire burns for a while. Fire is a hit.

Bars every lane but one and turns. Dash every slab down, one lane at a time, or it opens on its own.

The last stage. Paving falls from above. An X and a growing shadow mark where it will land.

Pulls creatures in from the lanes beside you.

Doubles the multiplier while it lasts.

Slows the whole world for a while. One pickup at a time, the new one replaces the old.

One life back. Offered only when a socket is empty.

Faster, and worth double while it lasts.
