ISSEN vs ISSEN 一閃

ISSEN is a calm-then-explosive samurai timing game. Breathe, focus, and release a single perfect stroke. In the stillness of a sumi-e ink world, one flash of the blade decides everything. THE WAY OF ONE CUT Wait for the moment. Swipe one arc to slash every target in range. A dead-center cut becomes a True Issen - time slows, ink bursts across the screen, and your combo soars. One stroke can cut several at once. A SUMI-E INK WORLD Hand-painted Japanese ink-wash visuals: black sumi ink, a single stroke of vermilion, and the beauty of empty space. Stillness and motion in sharp contrast - quiet calm, broken only by the flash of your blade. BREATH AND FOCUS Land True Issen cuts and keep your combo to fill the Breath gauge. Release it to enter focus: the world slows, the cut window widens, and you chain huge combos in the decisive moment.
