What’s in the game
Core loop. Tap the cosmic orb to earn Stardust ✦. Buy generators that earn Stardust automatically — even when the app is closed. Offline earnings catch you up when you return.
Seven cosmic tiers. Stargazer → Astronomer → Astrophysicist → Cosmologist → Galactic Cartographer → Architect of the Void → Demiurge. Each tier grants a permanent earnings multiplier that survives even Big Bang resets.
Big Bang prestige. Hit the lifetime Stardust threshold and reset your generators for Cosmic Shards ◈ — each granting +2% permanent earnings, compounding across every prestige.
12 generators, 36 upgrades. From Backyard Telescope to Demiurge Engine. Three escalating upgrade tiers per generator plus two late-game global multipliers.
No accounts. No analytics. No tracking by the developer. Single-player idle. Your save lives on your device and in your private iCloud account. Apple StoreKit handles purchases; Google AdMob may serve ads if you haven’t purchased Remove Ads.
