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.
Focus Knight is a relaxing focus and productivity RPG. Set a timer, stay focused, and watch your hero automatically explore dungeons, fight enemies, and grow stronger. The longer you focus, the greater the rewards.
Focus Knight is a relaxing focus and productivity RPG where every minute of concentration becomes real progress inside the game.
While you study, work, or create in the real world, your hero explores dungeons, fights enemies, collects items, and evolves automatically.



During focus sessions, your character:
Explores living dungeons
Fights enemies and bosses
Encounters random events
Collects equipment and treasures
Progresses automatically
The longer you stay focused, the greater the rewards.



In addition to the solo experience, Focus Knight also offers cooperative sessions, allowing you to focus and play together with friends.
Share focus sessions
Progress side by side
Turn study and work into a light social experience
But if you prefer to play alone, you are never truly alone.
During solo sessions, your pet will always be by your side, following your progress, reacting to your sessions, and keeping you company.
It doesn’t replace friends — it completes the experience, making focus feel lighter and more welcoming.
Whether you focus alone, with your pet, or together with friends, progress happens naturally always at your own pace.








Throughout your journey in Focus Knight, you will have access to more than 150 different items, including:
Equipment and weapons
Crafting materials
Gems and special items
These items can be obtained through enemy and boss drops, events during focus sessions, dungeon exploration, and crafting and equipment upgrade systems.
NPCs play a central role in the experience: they bring life to the world, offer services, unlock new features, and provide daily and weekly quests, encouraging steady and natural progression over time.
Everything connects to turn every focus session into meaningful progress inside the game.
