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.
Alone on a floating island in deep space, you use your telescope to study the universe, capture what you find, and confront the growing sense that something out there is aware of you.
Observa is a quiet space-photography game set on a small floating island suspended in endless darkness. You’re alone out here, with nothing but your telescope, a printer, and a silent sky full of things that shouldn’t always be there.
Point your telescope into the void. Search for planets, stars, drifting nebulae, and stranger objects that don’t have names yet. Capture what you find. Print your photos. Build up a gallery of discoveries that feel beautiful at first… and then start to feel like they’re watching back.
This world doesn’t tell you much. There’s no comforting voice guiding you, no busy city nearby, no hint of where “home” even is. Just quiet machinery, distant starlight, and the uneasy feeling that something out there knows exactly where you are. Somewhere in the darkness, something is moving. Something is coming. And you’re the only one who can see it getting closer.
Sell your photos, slowly improve your observatory, and expand what you can reach with your telescope. Not for power, not for glory, but because you need to understand what’s out there… and whether you have time left to escape.
Build your own gallery, fill it with proof of the universe around you, and decide whether your photos are comforting, or evidence of something you were never meant to witness.
