THE SKYDECIDES

Watch worlds breathe.

Watch worlds burn.

A 2D top-down pixel simulation where living ecosystems rise and fall under the sky you design. Shape the climate. Watch life evolve. Then stand back and let the world decide the rest.

FEATURES

WHAT LIVES IN
YOUR WORLD

Every system feeds every other. Pull one thread and watch the ecosystem unravel — or flourish.

SIMULATION

Living Ecosystems

Countless plants and animals compete for resources, reproduce, and go extinct — all simulated in real time. Every species is a thread in a living web that can unravel at any moment.

GENETICS

Evolution Engine

Heritable mutations pass traits across generations. Species adapt to climate shifts, predation pressure, and resource scarcity — or disappear forever.

TERRAIN

Dynamic World

Stream-power erosion carves valleys. Groundwater buffers droughts. Hydrology flows downhill in real time. A rich spectrum of biomes emerges naturally from the climate you build.

CLIMATE

Fire & Seasons

Design fully customizable seasons — each with its own temperature, rainfall, wind, and sunlight. Then watch the world respond: drought cracks the soil, storms flood the valleys, and disaster reshapes everything you built.

WEATHER

Climate Simulation

Temperature, precipitation, sunlight, and wind interact every frame. Biome classification updates dynamically as conditions shift. No two playthroughs share the same sky.

VISUALS

Pixel Perfection

Detailed 2D top-down retro art with day/night lighting, ambient shadows, and a renderer built for high organism counts. Old-school soul, modern simulation.
