Best on a computer

You sit at a green hacker terminal, pick an operator handle and use commands like scan and connect to reach THE SYSTEM, a rogue AI behind four security layers. The firewall makes you retype rotating bypass codes before they expire while a trace meter fills, the cipher hides a passphrase inside a scrambled transmission, and the memory layer has files to open and read. All the while, the AI uses your handle, fakes a reboot and leaves unsettling messages. The creator says a run takes about 5 to 10 minutes. Best on a computer: it needs a keyboard.

How the creator made it

The creator started with an empty project and asked Claude Code with Opus 5.5 to make a text-heavy horror game and keep some features secret until the first playtest. They say their only input before trying it was that prompt and answers to two questions about tone and length. They later asked for a glitchy boss fight, and the devlog says the game builds its scenes from code at runtime.

The prompt

I want to make a scary hacking game that gives AI vibes. And it would be even more fun if you can hide some of the features for me so you can surprise me when I playtest it. I didn't add any art assets, so you will have to get creative with those. I imagine a text heavy game that has scary effects and animations to give that hacker vibe sort of like the matrix. I don't want the game to be complicated but add scary elements and unexpected game behavior. The main goal of the game will be to hack "The System" So completing that will be the end of the game. Any ideas if you can make this work?

This is part of the prompt; the creator didn't share all of it.
