About this game

I am a middle school student in Shenzhen. I love The Three-Body Problem, black holes, and Star Trek. I built this game together with an AI, with a lot of help from my dad. Here is how it happened.

1. Why I wanted to build this

I have re-read the part of The Three-Body Problem where the Droplet annihilates humanity’s fleet many times. Later, watching Interstellar, I could not look away once Gargantua’s accretion disk lit up. Same with the Enterprise in Star Trek: what I cared about was never the plot, but what it would actually feel like to sit in a ship and fly close to a black hole.

I had played a few space games, but the black hole was either just a texture, or the game was so hard I quit in the first minute. So I wondered: could I make something you open in a browser, with a real black hole spinning in the middle of the screen, one that actually drags your ship around?

2. I could not really code

I started from nothing. My dad installed an editor, showed me how to run the page from the command line, and sat with me reading error messages line by line. The actual code was written by an AI: I described what I wanted sentence by sentence, it wrote the code, and my job was to play it and say "no, that part is too bright", "the handling feels floaty", "the black hole should be darker".

So the whole thing worked like a craft project: I described the picture and the feel, the AI turned it into something that runs, and my dad made sure I did not break the computer.

3. It was rebuilt over and over

At first there was only the Droplet — one ship for everything. Then I asked "could you choose a ship?", and now there are 11: from the Droplet and the Eridani ship to the Millennium Falcon, the Enterprise and the Executor, each with its own armor, acceleration, hitbox and fuel.

Gravitational waves started as ripples on screen. I told the AI "it should actually grab the ship", and that is where the speed loss and the sliding toward the black hole came from. I insisted the Hawking radiation peak hold for 5 seconds — otherwise there is no time to react and it is just unfair.

4. What it is now

11 ships, 10 singularity echoes, an 18-second Hawking radiation cycle, gravitational waves that both hurt and drag you, slingshots that reward hugging the disk, and a global fleet ranking (top 20). All of it runs in a browser — nothing to install, just open it and fly.

5. A last word

If you also think black holes are beautiful, come fly a lap.Pick a ship — hug the accretion disk for a while and see whether you can take ten echoes out through the gate. If you find a bug, or want a particular ship, I would love to hear it: this game was built out of one "could you also…" after another.

Thanks to my dad, and to the AI I made redo everything over and over.

I was never trying to make an impressive game. I just wanted to turn a few pages of The Three-Body Problem into a place you can fly through yourself.
