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.

Ruyn HD is a remake of my minimalist boomer shooter Ruyn, rebuilt in Unreal Engine 5. It keeps the fast, combo-driven gameplay of the original, but now features modern visuals, smoother controls, updated audio, and tighter gunplay. Ruyn Classic and the 2D and 3D level editors are included.

What is it?

Ruyn HD is a remake of my minimalist boomer shooter Ruyn, rebuilt in Unreal Engine 5. It keeps the fast, combo-driven gameplay of the original, but now features more modern visuals, smoother controls, updated audio, and tighter gameplay.

The levels are short, intense, and built for momentum—just you, some weapons, and a ton of enemies to blast through. The focus is on pure, simple shooter mechanics: fast movement and nonstop action.

The original Ruyn Classic is included, and the level editors work across both versions, so you can build once and play in either style.

Ruyn HD is 100% free — no ads, no microtransactions, no DRM.

The original Ruyn Classic, the 2D/3D level editors, and the launcher are all open source and public domain. The HD version's Unreal Engine code is not open source due to engine licensing restrictions, but everything else is yours to modify, share, or build on.

How do I play it?

The basic goal is simple: eliminate all enemies and reach the exit.
If you're chasing a high score, it’s all about speed, variety, and combo flow.

Each time you kill an enemy, a combo bar appears at the top of the screen—it drains quickly. Kill another enemy or collect a gem before it runs out to keep your multiplier alive. The longer you maintain it, the higher your score climbs.

But there’s more: the game rewards creative kills. Use different weapons or methods to earn style bonuses. Repeating the same kill type will reduce the bonus—so keep it fresh if you want to score big.

There’s also a bonus for finishing the level quickly, so don’t hang around too long.

Note: Ammo is shared over multiple weapons. When you collect some shells, you have access to the shotgun and double barrel shotgun straight away. This works the same for the plasma which is shared across the plasma rifle and trident.

Tip: Use the single-barrel shotgun when you need something that fires fast and the double-barrel shotgun when you need more grunt. This can help when you're trying to keep up a combo.

How do I make and share my own levels?
