Overview

Grow your own planet by tapping: each tap grants one day of life. The world starts as a molten lava ball under meteorites, then cools into crust, oceans, forests, and city lights. Buy core, time, and cosmos upgrades, unlock eras, catch space events, and collapse the world into a singularity for aether. The planet keeps living while you are away. Ads only give extra boosts; you can play without them.

Game instructions

Tap the planet to grant days of life. Open Upgrades: Core makes taps stronger, Time grants days every second, Cosmos adds crits and bonuses. Watch the era label above the planet — the look changes from lava to a stellar garden. In Boost you can watch an ad for a temporary bonus or reset into New Cosmos and keep aether. Achievements and the chronicle unlock as the world grows.
