Guide: Installing F.E.R.Y.L. on Linux with Steam Proton

This guide describes how to use Steam Proton to play and run Windows games on your Linux computer. Some games may not work or may break because Steam Proton is still at a very early stage.


1. Activating Steam Proton for Linux:
Proton is integrated into the Steam Client with "Steam Play." To activate proton, go into your steam client and click on Steam in the upper right corner. Then click on settings to open a new window. From here, click on the Steam Play button at the bottom of the panel. Click "Enable Steam Play for Supported Titles."

Alternatively: Go to Steam > Settings > Steam Play and turn on the "Enable Steam Play for Supported Titles" option.

Valve has tested and fixed some Steam titles and you will now be able to play most of them. However, if you want to go further and play titles that even Valve hasn't tested, toggle the "Enable Steam Play for all titles" option.


2. Choose a version
You should use the Steam Proton version recommended by Steam: 3.7-8. This is the most stable version of Steam Proton at the moment.


3. Restart your Steam
After you have successfully activated Steam Proton, click "OK" and Steam will ask you to restart it for the changes to take effect. Restart it. Your computer will now play all of steam's whitelisted games seamlessly.


4. Launch Stardew Valley on Linux:
Before you can use Steam Proton, you must first download the Stardew Valley Windows game from Steam. When you download Stardew Valley for the first time, you will notice that the download size is slightly larger than the size of the game.
This happens because Steam will download your chosen Steam Proton version with this game as well. After the download is complete, simply click the "Play" button.

What is F.E.R.Y.L.? Features and Description

Feryl is an experimental digital life simulation. A small creature lives in a glass terrarium on your desktop. It explores, plays with objects, responds to your voice, and sometimes challenges you to tic-tac-toe.

About This Game

Feryl is a tiny digital creature that lives in a terrarium on your desktop.

It isn’t animated or scripted — its behavior emerges from a continuous simulation driven by an internal rhythm.

You can watch it explore, speak to it through your microphone, or try to play games with it.

Overview

Feryl is a very small digital creature that lives in a glass terrarium on your desktop.

It is not animated or scripted. Feryl is an experimental digital life simulation.

Feryl runs on a stochastic internal rhythm — a forever-repeating breath cycle that is always unique and drives everything it does: where it looks, when it moves, what it pays attention to, how it reacts, and how it learns about the world around it.

You can watch Feryl explore its enclosure, try to engage it with games, or speak to it through your microphone and see how it responds.

Features

A Living Digital Creature

Feryl is less a traditional game and more a small system you share space with.

Feryl’s behavior emerges from an internal rhythm rather than scripted animations. Its movement, attention, and curiosity arise from a continuous simulation running beneath the surface.

The autonomous system that drives Feryl — perception, attention, speech, breathing, and behavior — fits in roughly 70 kilobytes.

A Terrarium World

Inside the enclosure are small objects, a friendly fly, busy beetles, and simple ways for you to interact.

You can observe Feryl interacting with its space and learn its relationship with everything inside: its vine, its couch, its rock, its mirror, and the sound of you speaking through the intercom.

Play Tic-Tac-Toe with Feryl

A tic-tac-toe board inside the terrarium allows you to try to play a game with Feryl.

Click the board to start a match. If Feryl becomes interested, it may approach the board and make its move. If you can keep its attention, you may even complete a full game.

Over time, Feryl gradually improves through reinforcement learning after each match.

Voice Interaction

Feryl can hear you through your microphone and may respond with sounds of its own.

Over time it adapts slightly to the vowel shapes and rhythms of the voices it hears.

Unique Creatures

Each Feryl begins from a seed, producing a creature with its own timing, tendencies, and behavior patterns.

Feryl states can also be exported as text codes, allowing you to preserve or share particular creatures and their environments.

A Quiet, Ambient Experience

Feryl is designed to exist alongside your desktop.

It doesn’t demand constant attention. Feryl lives in its terrarium. Whenever you have a moment, it’s there — even if it’s distracted.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

AI-assisted tools were used during development to help create certain store assets and to assist with portions of the program’s source code.

The shipped game does not generate AI content during gameplay and does not connect to external AI services.

Visual effects and imagery in the game are generated deterministically by the program’s code using mathematical and procedural rendering techniques (ASCII graphics and SDL-based visual effects). These systems do not use generative AI.
