KASANE
kah·sah·neh — layering

Layers of pigment, one over another. You see only the finished canvas — deduce the order they were painted, and the koi climbs the river.

One rule, a hundred pools

Every canvas in Kasane was painted one rectangle at a time, each layer covering what came before. Your task is to read the layers back — and every puzzle is verified to have exactly one answer, so it is always deduction, never guesswork.

Five seasons on one river

A hundred pools climb from spring through summer, autumn, winter and night, each season its own stretch of the river. Cross between them and the landscape redraws itself in ink before your eyes. Beyond the last pool lies Open Water, where the puzzles never end.

Made to be calm

No timers pressuring you. No forced ads. Gentle water, a koto phrase when the season turns, and a koi that climbs as you do.
