About

Astra Idle

Read full description

A dying spark. One planet. Then a universe. Astra Idle is a space idle game about growing a single star into a galaxy, and then collapsing it to start again, bigger. Feed the star, pull worlds into orbit, and watch the star-dust pour in while your phone is in your pocket. THE LOOP Feed the star. Unlock a planet. Level it up. Watch the numbers climb, and climb, and climb. When your galaxy can't grow any further, collapse it in a SUPER NOVA and rebuild it stronger. When even that stops being enough, trigger the BIG BANG and ascend into an entirely new universe. 24 WORLDS, 15 UNIVERSES From Terra to Empyrean, twenty-four hand-painted planets orbit your star, each on its own ring, with its own trail and its own rhythm. Beyond the Big Bang wait fifteen universes: Origin, Ashfall, The Long Dark, Ruinlight, Singularity's Edge. Every one of them has its own painted sky. LEVELS YOU EARN, NEVER BUY Cosmic Level is the one track in this game you cannot purchase. It comes from playing, and it pays Skill Points into a 49-node constellation you can grow in any direction you like. No shortcut. No bundle. No pay-gate. It survives every reset, including the ones that delete everything else. IDLE THAT ACTUALLY IDLES Your star keeps burning while the app is closed. Come back to banked star-dust, finished research on the bench, and comets waiting to be caught. DEPTH, IF YOU WANT IT - THE LAB: research priced in real time instead of currency. 70+ permanent upgrades that survive every prestige. - CARD COLLECTION: collect and fuse cards that automate the busywork. - TWO PRESTIGE TREES: 30 endless upgrades between them. Nothing in this game ever reads "MAXED". - 115 OBJECTIVES: a chapter-by-chapter chain that unlocks ten features, one at a time, so nothing arrives all at once. - THE COSMIC LADDER: a lifetime ranking ladder with six prize brackets that pays out every week. - 51 COSMETICS: 25 stars, 15 skies, 6 orbit trails and 5 planet skins to earn and wear. BUILT FOR ONE THUMB Portrait. One hand. Sixty-second check-ins or sixty-minute sessions. The star doesn't mind either way. Free to play with optional in-app purchases. Rewarded videos are always your choice, watch one only when you want the bonus. Grow a star. Break a universe. Do it again, bigger.
