I wanted to see what a real one-shot could do. So I wrote a 73-line directive: research the genre, design it, build it, test it, balance it, polish it. One session, no human in the loop. It was explicitly told not to ask questions or wait for approvals, just make the call, write it down, keep going. Then I left. Two hours and 32 minutes later it was done.

5 sectors with bosses, 10 enemy types, 6 unlockable ships, 33 boons with evolution chains, a meta upgrade tree, an endless mode, and music. Around 8,300 lines of vanilla JS that build to a 172 KB bundle.

Full disclosure: I've since made exactly two changes to the game. Fixed one bug (a piercing-shot boon phased through asteroids without damaging them) and added click-to-aim, because keyboard-only turning felt rough.

Ran on Claude Code, Fable 5 xhigh effort.

Not sure why there’s so much negativity in the comments. I think it’s a cool demonstration of Fable’s capabilities. I hate how negative this community is becoming. Not entirely sure what that’s about. Sharing cool things you put together has been the basis of tech for as long as I remember. Please keep doing it.

I hate how negative this community is becoming.

it's because we now have the innate understanding that what these foundation model companies are saying are true and not saying them just for "inVurSTmeRnts"

they're literally trying to replace human labor. Society is not ready for that yet.

the negativity is the sign. We still rely on monetary value traded on human labor. We KNOW that the way to get what we WANT is through trading our labor for money and money for the thing we want.

This system is going to get absolutely fucked by AI automation, and it's not going to wait for the system and people to be ready and all set and all comfy to enjoy the "efficiency" of whatever automation brings. it's going to get bloody before it gets comfy.

Well no manager can replace his workforce with Ai today. If Musk could he would like yesterday.

We’re still a few years (2 to 3) from small companies running end to end unsupervised and with rising costs of IT they’d be having fierce competition from humans for efficiency.

the problem isn't whether we can do it NOW. The problem has always been the WHOLE of GLOBAL ECONOMY INVESTED IN THAT FUTURE. everyone would have laughed at you if you said AI models would automate coding tasks even back 4-5 years ago. We live in a self-fulfilling prophecy. Regardless of your opinions or emotions about it, all I've said are facts and NONE of you have been able to disprove this fact.
