About this game

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

1. Why I wanted to make 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 have played a few space games, but the black hole was either just a texture, or the game was so hard that I gave up in the first minute. So I wondered: could I make something you can play by opening a web page, with a black hole actually spinning in the middle of the screen and a ship that gets pulled by it?

2. I do not actually know how to code

At the start I knew nothing. My dad installed the editor, showed me how to run the page from the command line, and read the errors with me line by line. The real code was written by an AI — I described what I wanted, sentence by sentence, it wrote it, I playtested, and then said "no, this is too bright", "the controls feel too 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 has been rewritten many, many times

At first there was only the Droplet — one ship for everything. Then I asked "could you choose a ship?", and now there are 11 ships: 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. What I want to say

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.

Thank you dad, and thank you to the AI I kept poking at.

What I wanted to make was never a "great" game. I just wanted to turn those few pages of The Three-Body Problem into a place you can fly through yourself.
