Mass Limit

You are a celestial body that must make its way from a small asteroid to a black hole. Explore a procedurally generated universe, capture objects into orbit or absorb them to gain mass and advance to new stages. Observe solar systems, life, and civilizations on planets: civilizations evolve and launch rockets at other objects, setting their development back to previous stages. The greater your mass, the stronger your gravitational pull. Reach the critical mass of a black hole and trigger the Big Bang, after which the game starts over. Asteroids, planets, stars, and black holes create a living, ever-changing cosmic environment.
