Sainokawara

Stack stones. A demon comes and collapses them.
The collapsed stones become "impermanence," and with that impermanence, you call upon Jizō.

An incremental/idle game playable in your browser, themed after "Sai no Kawara" (The Riverbed of Souls).

It begins simply with just stacking stones, and gradually Jizō, intention, foresight, samsara, and karma are unlocked.

"Foresight" allows you to collapse the tower yourself before the demon arrives. As you continue playing, the riverbed's appearance changes through idle progression, weather and visitors, rare stones, and ferryboats.

Supported in Japanese, English, Traditional Chinese, Simplified Chinese, and Korean. Playable on both PC and smartphones.

Rather than pursuing flashy strategies, it's a game where you watch the act of stacking and having stones collapse, as the world gradually transforms around you.
