A daily god game, in the browser or on a phone, no account. You are a hand over an island: hold on the land to scoop sand, water or lava, hold again to pour it. A tribe settles three towns; seven waves roll in from the south, and every wave lifts the sea for good. Build walls, and tap a town to send its people up to the altar on the ridge before the water cuts them off.

Each UTC day has one sea: the waves come at the same times and sizes for everyone, so scores compare. Your score is everyone who reaches the altar or still stands when the last wave ends; the share button gives a line like "Sea 2: 14 of the salt people safe". The best so far is 35.

A round takes a few minutes. The island, the people and the ink look are drawn in its own code. Post your sea here; I read every reply, and what drowned your town tells me what to fix.
