About Mass-Energy: Planet

Mass-Energy: Planet is a space survival simulator where a single celestial body — starting as a humble asteroid — evolves toward becoming a supermassive black hole. Photorealistic 3D graphics and sci-fi aesthetics frame a relaxing yet strategic sandbox that explores the physics of scale, energy, and gravity. Simple drag controls keep the experience accessible whether you have a few minutes or a few hours.

How to Play Mass-Energy: Planet

Navigate your player planet by holding and dragging — absorbing mass and energy causes it to grow. Release to stop movement entirely. The journey traces a path through cosmic evolution, from asteroid to apex gravitational force in the galaxy.

Other space games worth exploring: Black Hole: Eat the Universe takes the same consume-and-grow premise to an incremental scale, letting you devour atoms and entire galaxies. Galactic Merge channels the cosmic evolution loop into a relaxed merger format, combining asteroids and comets into ever-larger celestial bodies. For something faster-paced, Cosmic Dash keeps the drag-to-navigate mechanic but cranks the speed up across a hazard-filled space run.
