About Inspiral: Echoes of Gravity
In 2015, LIGO made the world’s first direct detection of gravitational waves with the event GW150914, confirming for the first time in history the existence of binary black hole systems.In most space-themed games, you pilot a spaceship or colonize planets. But in this game, you become a celestial body. Start as a lonely asteroid, grow by absorbing smaller objects, and evolve step by step—from asteroid to planet, to star, and ultimately to a black hole that devours everything. All of this unfolds in a vast sandbox universe driven by real physics.Gain mass by absorbing smaller asteroids and progress through multiple cosmic stages, each unlocking new abilities and challenges:
- As a planet, nurture life and protect your own world;
- As a star, your powerful gravity can capture planets and build your own planetary system;
- As a black hole, nothing can escape your grasp.
Key Features:
- Cosmic Growth System: Evolve from an asteroid to a planet, a star, and finally a black hole, each stage offering unique gameplay and abilities.
- Realistic Physics Simulation: Experience lifelike gravity and orbital mechanics—construct stable planetary systems or trigger spectacular collisions and chaos.
- Dynamic Sandbox Universe: An ever-evolving universe where new celestial bodies and events continually emerge, and cosmic evolution never stops.
- Explore the Binary Black Holes: As the binary black holes grow and spiral toward each other, will you survive—or be swallowed by the void?

plays like a basic gravity demo and one still in the alpha stages at that. to quote some community notes i saw after being disappointed "i could get more out of a 25c ramen packet"
A game where you start as a little asteroid and grow up to become a black hole. I've made it up to 135k mass and haven't found anything further. For it's price, it's a fun little game but as a star, planets orbiting you randomly disappear, which is very disheartening.
Is this a terrible game? No. Is it a great game? No. It hovers in the middle ground of novelty and playability. A simple but engaging design wherein the player collides with other asteroids to accumulate mass. It then, however changes the established gameplay rules where rapidly smashing into other celestial objects penalizes the player by reducing mass. You have to slowly approach and trap satellites into your orbit and then press a key to absorb them. None of this explained. It is a frustrating trial and error approach over the span of about an hour. While the achievements are simple progression and the title itself is appropriately priced, I cannot recommend this game, even as a time waster.
