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.
Developed by creator Project FW, this is a dungeon-exploration RPG! In the world of Filtwiz, humans and demons are locked in relentless conflict— yet a new, threatening third force quietly rises: the Erosion, In the vast labyrinth, the feast of evil girls opens wide… the adventure begins!

In the world of Filtwiz, humans and demons are locked in relentless conflict—
yet a new, threatening third force quietly rises: the Erosion,
creatures that don’t merely prey on humans, but hunt demons too.
The real leader of the demonkind, the Second Demon General known as the Grave Digger,
senses the rising danger and dispatches the elite “Grave Digger Royal Guard”
into the ramshackle depths of the Aberrant Maze, where Erosions now flood forth.
Among them stands Lyuelle, the lowest‑rank member of the Guard,
who sees this mission as her golden opportunity to change destiny and distinguish herself.
With her loyal underling Flamme at her side, she boldly steps into the maze—
a journey toward power begins.
In the vast labyrinth,
the feast of evil girls opens wide…
the adventure begins!








◆ Begin the Adventure from Your Base
In Lyuelle’s hideout you’ll find a variety of activities:
craft items, turn in quests, interact with companions.
Use these well to make conquering the maze much smoother!
As more allies join you, you can even cultivate an underground garden to harvest materials for synthesis.
◆ Territories of Different Demon Clans
Beyond Lyuelle's hideout lie multiple demon‑clan strongholds.
Befriend other demonkind, gain their support—
and pick up treasures scattered across the map while you’re at it.
◆ Maze Exploration
Venturing into the Aberrant Maze is no simple stroll.
You’ll need to steadily accumulate experience,
recover valuable materials and treasure chests,
and strengthen your squad!
On each floor lies a hidden room—
discreet yet full of loot, sometimes even concealing characters…
◆ Formidable Foes in the Maze
Every layer of the maze conceals powerful bosses!
Acquire intel from the Owl Sage to discover how to beat them!
During battle you’ll see enemy actions and HP bars—
careful observation and smart choice of actions are your keys to victory!
Not only Lyuelle, but other Royal Guard members will appear in the maze!
Defeating higher‑rank guards earns you fame and boosts your ranking!
As your rank rises, you’ll become a renowned demon—
others’ attitudes toward you will improve,
and new demon‑territory areas will gradually unlock.
◆ Advance Toward the Summit!
In your stronghold you can check your gallery for acquired items and encountered enemies!
Collect powerful equipment called “Cubes” to customise your characters as you like!
When characters reach level 30 or above,
you can perform a “Class Change”!
With enhanced power and your own established tactics, you’ll stand undefeated!
As you explore deeper floors, the Owl Times updates, and companion dialogues evolve.
Repeat dungeon exploration and base preparation—
your goal: become the strongest demon in Filtwiz!
This is your tale—venture boldly, collect power, and dominate the abyssal labyrinth.
Rise and claim your place at the top of Filtwiz.
