Hack://TheSystem

This game was entirely made by Claude Opus 5.5. I made one initial prompt for a scary hacking game:

"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?"

Claude did the rest. It was a fully empty game project and I didn't tweak anything except answer two questions:  What type of scary (unsettling or jumpscares) and length. I answered unsettling and length about 5 to 10 minutes. 

Enjoy!

[UPDATE 24-10-2026] 
I've asked Claude to add a BOSS fight, because what's a game without a proper boss fight? So now I can't beat the game anymore because the boss is too hard T_T. Anyone who wants to give it a try?
