About the Game
How To Grow a Black Hole is a chill incremental game about feeding, upgrading, researching, and barely controlling the most dangerous cosmic object imaginable.
Start small, increase your mass, unlock new ways to grow, and push the numbers higher and higher until everything starts getting completely unreasonable.
It is simple, strange, satisfying, and built around one important question:
How big can you make it before everything goes wrong?
Feed. Upgrade. Barely Keep Control.
Start with a tiny black hole.
Feed it.
Grow its mass.
Unlock stronger upgrades.
Research new systems.
Push the numbers higher.
Try to keep it stable.
Watch everything get completely unreasonable.
