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.
TRAILER COMING SOON
A world that lives, breathes, and evolves in real time
Real-time ecosystem footage — a dense, living biome under active climate pressure, with organisms competing and disaster spreading across the terrain.
[HD 1080p]WHAT LIVES IN
YOUR WORLD
Every system feeds every other. Pull one thread and watch the ecosystem unravel — or flourish.
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.
Evolution Engine
Heritable mutations pass traits across generations. Species adapt to climate shifts, predation pressure, and resource scarcity — or disappear forever.
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.
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.
Climate Simulation
Temperature, precipitation, sunlight, and wind interact every frame. Biome classification updates dynamically as conditions shift. No two playthroughs share the same sky.
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.
