This is an interactive gravity simulation where you create celestial bodies and observe their real time interactions. Choose a tool from the panel including planets, stars, black holes, or asteroids, then click and drag with your mouse to set the initial velocity of each object. Gravity affects all bodies, causing them to attract, collide, or form orbital systems, while black holes consume everything nearby. Use antimatter for explosions, the beam for targeted destruction, and the gravity gun for pushing objects away. The interface shows body count, particle count, and frame rate, while the inspector panel lets you modify the parameters of a selected planet in real time. Toggle motion trails, adjust simulation speed, and build complex systems using the built in solar system preset. The game offers creative freedom for experimenting with cosmic physics and modeling.
