Cosmic Sandbox

A space sandbox where you control gravity and build your own systems of planets, stars, and black holes. Each object is made of pixels and has internal layers: crust, mantle, and core. Under gravitational forces, objects can deform, break apart, and reveal their inner structure. Experiment with mass, velocity, and rotation, observe orbits and interactions between bodies. Create stable systems or chaotic space experiments — everything follows physics and your input.
