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.

Light is oppression — survive between the light and the shadow

As a vampire, you joined an expedition of your kin into the fabled Hollow of the Angel, lured by the possibility of priceless blood crystals known as Tears of the Angel. Your kind's unique vision made navigating the pitch-black tunnels effortless, and soon you reached the mine’s deepest layer—the mineralized zone.

But the moment the blood crystal was extracted, everything changed. The shaft collapsed, madness overtook your companions, and worst of all: the once-dark underground world is now filled with blazing light. Even a single misstep into its searing glow could mean instant death.

You must tread carefully, using every shadow for shelter, and mastering the dance between light and darkness to stay alive.

Logic is hope — solve the puzzles and find your way out

You awaken amidst the ruins, realizing you've been attacked and abandoned by your maddened companions. Familiar corridors have twisted beyond recognition—what was once a clear path is now riddled with deadly traps and shifting mechanisms.

Can you remain calm enough to navigate the chaos?

Threat is weapon — when faced with danger, you've known how to strike back

What will you do when you stand before IT？

“The level design is well-structured and full of ingenious ideas. The physics system is also impressively handled.”

“The camera handling really stands out—honestly more polished than in many commercial games. During each puzzle or platforming sequence, the camera stays steady and focused, and when the player reaches a new puzzle, it shifts smoothly to match the new context.”

“Objects often serve multiple functions—some elements must be avoided, yet can also be cleverly used to your advantage. You can really see the thoughtfulness and experience behind the design.”
