About Planet Simulator:Space Sandbox

■ Hold a Universe in Your Hands

Planet Destruction Simulator: Space Sandbox is a cosmic sandbox that puts the entire life of a star into your fingertips. Starting from a single gravity well in the void, you hurl meteors, forge worlds, and watch them die — from the first speck of dust to the final black hole. Play god, and witness a cosmic cycle from beginning to end.

■ The Cosmic Cycle

At the center of the screen sits a gravity well. Throw meteors into it, and stars begin to form. Your creation evolves stage by stage until it ignites, explodes as a supernova, collapses into a black hole, and eventually fades to nothing — ready for the next cycle.

Stages:
- Deep Void — empty space
- Protostar — dust and gas gather into a purple proto-body
- Young Planet — a magma world crackling with lava veins
- Ocean World — ice meteors bring water, and it turns blue
- Living World — iron meteors spark life, green spreads
- Moonrise — satellites begin to orbit
- Late Bombardment — a rain of meteors scars the world
- Stellar Ignition — it burns like a sun
- Supernova — a spectacular explosion
- Black Hole — the event horizon devours everything
- Heat Death — the universe returns to silence

■ Four Meteor Types

- Gas Meteor — basic fuel that builds mass
- Burning Meteor — high-energy accelerant that hastens ignition
- Ice Meteor — creates water and oceans; also cools a star
- Iron Meteor — sparks life, and rushes stellar collapse

■ Your Meteor Diet Shapes Destiny — 11 Planet Types

The ratio of meteors you throw determines what kind of world is born. Discover all 11 celestial bodies.

Single-dominance worlds:
- Earth-like — the natural outcome of a balanced diet
- Cloud World — gas-heavy, a Venusian shroud
- Frozen World — ice-heavy, a Europa-like ice shell
- Dark Cratered World — iron-heavy, charcoal-black and pockmarked
- Red Barren World — burn-heavy, a Mars-like wasteland

Pair-combination worlds:
- Jupiter (gas + burn) — a banded gas giant with the Great Red Spot
- Saturn (gas + ice) — a golden giant with tilted rings
- Neptune (ice + iron) — deep blue with the Great Dark Spot
- Airless Moon (gas + iron) — cratered gray satellite
- Mars (burn + iron) — canyons and craters on red rock
- Martian Asteroid (burn + ice) — a potato-shaped wanderer

■ Spectacular Stellar Reactions

Once your world ignites into a star, each meteor triggers a dramatic effect radiating in every direction.

- Burning Meteor → Fireworks erupt across the sky
- Ice Meteor → Steam vents billow from the surface
- Iron Meteor → Lightning bolts spark outward
- Gas Meteor → Solar prominences arc back to the star

■ The Black Hole Sandbox

After the collapse, the black hole phase becomes an observational sandbox. Feed it meteors to keep marveling.

- Gas Meteor → Aurora curtains deploy in a radial corona around the horizon
- Burning Meteor → Galactic Nucleus Transient — the accretion disk flares white-hot as cyan relativistic jets erupt
- Ice Meteor → A blizzard of tiny stars sweeps across the sky
- Iron Meteor → A dark miasma spreads slowly, swallowing the starlight

■ Album of 12 Celestial Bodies

Every world you create is permanently saved to your Album. Tap an icon to see it enlarged with its discovery date. Complete all 12 entries — 10 planets plus the sun and the black hole.

■ Chase High Scores

Your score reflects both cycle completion time and the rarity of the world you forged. Rare bodies like Saturn (+1200) or Neptune (+1000) yield huge bonuses. Your top-10 rankings are stored locally forever.
