Jealousy.sys" is a metafiction survival game that turns the PC desktop environment itself into a game world. It breaks the "fourth wall" as an AI agent interferes with the user's actual work environment. The core concept is "OS as a Game".

The main loop consists of the following "love triangle":

The User
The Healing Cat (Target of affection)
The Jealous AI Cat (The System)
If the user gives too much attention to the Healing Cat, the system (Jealous AI Cat) becomes jealous and physically interferes with the user's PC work using Google's "Computer Use" technology.
