I made a small god game for the browser, phones too, no account. You never command the tribe: you are a hand over an island. Hold on the land to scoop up sand, water or lava, hold again to pour it. The tribe walks to three hearths on its own; then a wave comes in from the south and a lava spring wakes on the ridge, and the only strategy is the shape of the land you leave them.
Sand walls erode, water finds every gap, and lava poured into the sea cools into rock that holds, so the question each time is what to spend the hand on and where. The first island takes a few minutes. After it there is the rising sea: the towns you hold grow, every wave lifts the sea for good, and you choose which town to send uphill before the water cuts it off.
Everything, the island, the tribe and the ink look, is drawn in its own code. I read every reply: what you tried that the water broke, and what would make the land feel more like a plan.
