Gachon Dynamic: ShellBits
A downloadable game for Windows and Linux
You weren't supposed to find this. Decrypted from a long-forgotten supply chain leak, ShellBits is a high-end, secretive software experiment from Gachon Dynamics. Part virtual companion, part terminal-based AI — this 1998 "Legacy R&D" project brings a persistent, stateful digital entity directly to your modern desktop.
A ShellBit is a deterministic digital organism assigned to your unique hardware signature. While their Bones — species, stats, and rarity — are hardcoded into the cryptographic architecture, their Soul — name and personality — is generated dynamically through a local neural link.
From standard Ducks and Cats to rare Axolotls, Dragons, and the mythological Moth (Legendary-only). Unlock 20 additional Diamond-tier organisms through long-term play.
Common to the elusive Legendary, with a base 1-in-100 (1%) chance for a "Shiny" chromatic variance. Earn the Shiny Charm to raise odds to 5%, 7%, or 10%.
Every unit ships with six calibrated values — Bravery, Intelligence, Clumsiness, Optimism, Snark, and Tech — each influencing how your companion expresses itself.
Units are assigned one of five operational profiles — Social, Play, Gourmet, Cleaner, or None — which affect gameplay bonuses and care rewards.
Forget modern minimalist UIs. ShellBits runs on a proprietary terminal-based framework built with React and Ink, delivering a 1998 corporate research aesthetic.
- ▸3D Legacy Rendering — Menus feature simulated drop-shadows and industrial segmented borders.
- ▸BIOS Boot Sequence — Hardware initialization, data packet decryption, and shell integrity calibration on launch.
- ▸Phosphor Palette — Full-color or monochrome accent modes optimized for CRT-style immersion.
- ▸Neural Log Archive — Context-aware chat where your companion reacts to care, game performance, and time of day.
- ▸Collection Tab — Three independently scrollable panels in one view: discovered species (with live sprite preview on hover), stamps collected, and your full roster — cycled with a single keypress.
Engage in specialized training exercises to earn Compute Credits and Bond XP. Five games are available from boot; the rest are unlocked through play, age milestones, and betting history.

Privacy is our primary directive. Unlike modern cloud-reliant assistants, ShellBits is powered entirely by local LLM integration (Ollama).
- [OK]No Data Harvesting — All interactions, context, and Soul generation remain on your local disk.
- [OK]Offline Intelligence — Your companion develops its personality and dialogues through your own local inference engine.
- [OK]System Stability — Built to morph and anchor across your desktop. Linux/Wayland and Windows launchers supported.
Gachon Dynamics is not responsible for any emotional attachment formed with experimental ShellBits. System anomalies may occur.
