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.
Marshmallow Marvin: Templestone is a challenging 2D pixel art platformer where you guide Marvin through trap filled ancient ruins, avoiding deadly spikes, dodging automated turrets, and mastering precision platforming to reach the exit.
Step into the ancient ruins of Templestone and help Marvin escape a perilous journey through crumbling temples and trap filled corridors. In this 2D pixel art platformer, you’ll guide Marvin across mysterious yet dangerous environments, collecting coins, avoiding hazards, and fighting your way toward freedom.
Your mission is simple: survive and reach the end of each level.
As Marvin, you’ll leap across platforms, dodge deadly traps, and explore every corner of Templestone in search of valuable rewards. Coins encourage exploration, while hearts restore your health giving you a fighting chance against the dangers ahead.
The early levels ease you into the adventure, helping you master movement and timing. But don’t get too comfortable each new stage ramps up the difficulty with more complex layouts, tighter jumps, and faster threats. Success depends on your reflexes, precision, and ability to adapt.
Templestone may be ancient, but it’s anything but safe:
Razor-sharp spikes that punish mistimed jumps
Moving traps that demand perfect timing
Automated turrets that track Marvin and fire relentlessly
As you progress, levels become more intricate and unforgiving, pushing your platforming skills to the limit.
With its retro pixel art style, Marshmallow Marvin: Templestone blends nostalgic visuals with an eerie, ancient setting. Crumbling stone pathways, hidden chambers, and deadly mechanisms create a tense atmosphere where danger lurks around every corner.
Every decision matters:
Take risky paths to collect more coins
Play it safe to preserve your health
Plan ahead to outsmart traps and enemies
Each completed level brings you closer to freedom—and deeper into the temple’s secrets.
Classic 2D platforming action
Trap-filled, increasingly challenging levels
Health recovery through collectible hearts
Enemy turrets that dynamically target you
