About Hack://TheSystem
A short psychological horror game about hacking, played mostly through text and typing; a session lasts a few minutes. The developer, Wietske, says the game was entirely made by Claude Opus 5.5 from one initial prompt, and that they only answered two questions about the kind of scares and the game length. The itch.io AI disclosure lists code, graphics, sounds and text as AI-assisted. It is free to play in the browser on itch.io.
How it was built
Partially verifiedThe developer says the game was entirely made by Claude Opus 5.5 from one initial prompt for a scary hacking game; apart from that they only answered two questions (type of scary: unsettling rather than jumpscares; length: about 5 to 10 minutes). The coding interface (for example Claude Code) is not named. The itch.io AI disclosure lists Code, Graphics, Sounds and Text.
One initial prompt to Claude, which the developer says built the rest; a later update added a boss stage.
