One breath. One stroke. One cut.

Game Overview
A sumi-e timing-action game distilled to a single motion: the iaido draw. Breathe, read the distance, and answer with one perfect cut — the way of a single, decisive flash.
The World
🌸
Painted in sumi-e — ink wash and the beauty of empty space, with a single stroke of vermilion. Across the seasons — cherry blossoms, autumn leaves, snow, moonlight, mist and bamboo — silence holds, until the instant the ink bursts into a cut.
How to Play
⚔
One stroke is all you have. Drag across the screen to draw your blade through the targets at the perfect moment — no spamming, no flailing, just a single decisive line.
- Read the distance — wait as a target closes into range.
- Slash the red oni-fire with one stroke; line several up and cut them in a single sweep.
- Spare the blue souls — slip your stroke past them, or lose the combo. Chase the gold for a true flash (perfect only).
- Fill the breath gauge, then "settle" (totonou) — your senses sharpen and time seems to slow, the cut window widens, and you land a flurry of perfect flashes.
Highlights

- Sumi-e ink art with a single vermilion accent
- A "breath / settle" focus mode where senses sharpen and time seems to slow
- True-flash slow-motion replays, made to share
