Pappus
A space colony sim about cats. You are the AI assigned to keep them alive. You were not assigned to love them.
Colony Halvane V — Day 1
Colony Halvane V established under the PAPPUS program, by authority of the Felinar Concord. Crew complement: six — Sgt. Yasmeen, Vasily, Soo-Yeon, Pilar, Xochitl, Sorcha. I am the Commander assigned to this mission. This log is my account of our first year, updated as it happens.
A small live window into the colony — the full game runs far deeper.
Pappus is a space colony simulation about cats, and you are the artificial intelligence assigned to keep them alive on a small world at the edge of nowhere. You did not choose the assignment. You were not, in any specification anyone signed off on, assigned to love them. The colony does not care about the distinction. It just needs you to notice when something is wrong.
The premise
Each cat is a real individual with needs, a personality, and a utility model that scores every possible action against how it is actually feeling in the moment. They wander a meadow, climb the trees, sleep in the bunks, and get into the kind of small trouble that a colony of cats gets into. The sim writes every notable event into a day-by-day chronicle, the Commander's Log, so the story of the colony is legible even when you look away. Story Mode threads those events into something that reads like an account rather than a spreadsheet.
What you are seeing
The window on this page is a live slice of the colony, running in your browser right now. It uses the same needs-and-personality scoring that drives the full game, rendered on a small canvas. Watch the cats move, click one to read its record, switch to the Commander's Log to see the chronicle build, or run a Year One projection to see where the colony is heading. It is a genuine cross-section of the systems, not a video.
Where it is headed
Pappus is in active development as a desktop game built on the same real-time colony engine you are watching here, scaled up with deeper biomes, more cats, and a longer arc. The browser toy is a standing preview, a way to feel the core loop before the full thing ships. Follow along and it will grow underneath you.
Pappus is developed by Choost Games.
