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.
It was supposed to be just a harmless chat to kill time with a stranger named Mina. But from the other side of the browser, the boundary between your reality and the internet is slowly being eroded. This is a desktop-invasion chat horror.
Sato Killing Time Chat.exe is a short-form ARG (Alternate Reality Game) mystery where players communicate with a mysterious girl named "Mina" through a chat interface. This isn't just a game inside a window—it’s an experience that bleeds into your real world.
Players launch a specific chat app on their PC and exchange messages with a girl named "Mina." An outcast at school and estranged from her family, she reaches out to you with a simple request: "Kill some time with me."
■ Story Progression via Chat UI
The game features a realistic messenger app interface. Through your conversations with Mina, you will gradually uncover the truth. The responses you receive adapt based on your own replies.

If I tell Mina something she dislikes, she might start keeping her distance...?
■ Web Browser Integrated Gameplay
Investigate a web of multiple fictional pages—furniture stores, news sites, social media, and corporate homepages. Everything is a clue leading to the "answer," from hidden codes and names to a single sentence in a comment section.
■ "Selfies" as Rewards
When you clear specific puzzles or phases, Mina—who is fully convinced of her own cuteness—will send you selfies as a "reward." Is this genuine affection, or is it manipulation?
