What the developers have to say:

Why Early Access?

“These Universes are still in progress with basic interactions. I am not very sure if it`s complete this time. What I plan for this game that Zen and peace you can get through these Universes. Most of all, it`s a procedural game design. Every thing in game looks random but have some patterns actually. Hope you guys could enjoy the progress. And I decided to develop side by side in collaboration with its community with the goal to enrich this game.”

Approximately how long will this game be in Early Access?

“One year at least.”

How is the full version planned to differ from the Early Access version?

“It depends on what players want to do. It`s basic concept wont be changed. It will add more life forms and civilizations and more AI objects. It will allow you to invade other players universe or setup your defense in your universe like a black hole, stars and something with really high gravity or energy. But still need to take care of quantum entanglement may break what you have planned.”

What is the current state of the Early Access version?

“Please refer to "About this Game" for details.”

Will the game be priced differently during and after Early Access?

“I plan to gradually raise the price as I ship new content and features. But it`s not every time I ship new stuffs.”

How are you planning on involving the Community in your development process?

“All posts and ideas will be examined by myself and I will try to give my best to respond. Every idea will be implemented in the game even it`s a bad idea. I will give it a chance. The best to communicate your ideas to me is by posting articles on the community hub or simply mail me.
Be patient, I`m the only crew. Good things come to those who can wait. The concept in the game is the universe simulation by basic interactions at the present. The plan is to gradually improve the gameplay and add more contents that players advised.”

About This Game

Four years have passed, and looking back, Universe999999 has always been closer to a personal experiment than a conventional game.

I started with an ambitious idea: to simulate the universe from a Big Bang, letting the four fundamental forces define everything that followed. Matter, energy, stars, and structures were meant to emerge on their own, guided only by underlying rules. During that period, I was deeply focused on one thing—whether the theory could be recreated, whether the system made sense.

For a long time, I convinced myself that this was enough. Watching a universe slowly take shape felt meaningful. But eventually, a quiet discomfort set in. There was beauty in the simulation, yet there was distance. Players weren’t shaping the universe—they were waiting for it. Observing instead of deciding. Understanding instead of acting.

That discomfort led to a difficult question I couldn’t avoid anymore: Was I trying to simulate a universe, or was I trying to make a game?
No matter how intricate a system is, if it doesn’t allow players to feel present—if it doesn’t let their choices matter—then something essential is missing.

Admitting that wasn’t easy. It meant accepting that years of work, while not wasted, weren’t pointing in the right direction as a game. But it also opened a new path forward.

The direction began to change. I kept the ideas of cosmic formation and structural evolution, but moved them beneath the surface. What came forward instead were decisions, trade-offs, management, and expansion. The universe stopped being something that merely happens—it became something that asks something of the player. Responsibility, involvement, and consequence became part of the design, along with a few philosophical questions I still don’t have clear answers to.

The current version of Universe999999 is undeniably different from what I first imagined. Yet for the first time, it feels like it’s asking the right questions: Is this engaging? Is this meaningful? What does the player take away after playing?

This update is only a moment along a much longer path. It includes early in-development visuals, and many systems are still evolving. To everyone who believed in this project early on and chose to support it—thank you for giving me the time and space to find what this universe was truly meant to become.
