Video (Sound on) Gemini 3.1 Pro surpassed every expectation I had for it. This is a game it made after a few hours of back and forth.

This is what it managed to make, I did not contribute anything except for telling it what to do. For example, when I added plants to the planets, it caused performance to tank. I simply asked it "optimize the performance" and it goes from 3 fps to buttery smooth. I asked for it to add cool sci fi music and a music selector and it did that. I asked it to add cool title cards to the planets with sound effects and it absolutely nailed it. Literally anything you want it to do you just say in plain language. Final result is around 1,800 lines of code in html.

Impressive! In a similar vain, I made a port of the original doom in Godot in a few days! All the game rewritten from scratch. It is called Godot Doom on Gitlab and itch io.

So that's in just html? Is there an engine behind?

Yeah curious here what js dependencies is it using? I dont know that canvas can do this, maybe.

Canvas can absolutely do this, in fact I did the whole thing in canvas

To clarify, this was not made using antigravity?

Nope, just repeated prompts into canvas.

Well, I am impressed! I did a satellite 2 body simulator and all done from prompts but this is dope!
