Overview

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.

Game instructions

Select space objects from the panel and place them in the scene. Set their initial velocity by dragging and adjust rotation. Objects attract each other and interact through gravity. Under strong forces, they can break apart, losing pixels and revealing inner layers. Zoom and move the camera to observe the simulation. Experiment with different object combinations to create stable orbits or dynamic interactions.
