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.
Daruma Observation Log is a roguelite observation sim where you breed darumas, harvest mysterious energy, and escape a collapsing facility ravaged by disasters to unlock permanent upgrades. Zero comfort, zero cuteness—just nonstop tension and brutal choices.
Daruma Observation Log is a roguelite observation simulation game in which you cultivate and observe inorganic beings called Darumas, collect mysterious energy, and decide when to escape from an experiment site on the verge of collapse.
This is an Energy Experimental Site. Here, mysterious energy is harvested when tiny beings known as Darumas vanish. Inside circular chambers, Darumas collide, reproduce, and eventually reach the end of their lifespan and disappear.
There is no stability in this facility. As time passes, disasters such as snowfall, lightning strikes, disease, fires, and violent gusts grow more severe, pushing the site into an uncontrollable state of chaos. If left unchecked, the only outcome is the total extinction of the Darumas and the complete loss of your results.
At the start of the game, you spend your funds to place circular chambers (petri dishes) and then place Darumas inside them.
Once placed, the Darumas begin moving on their own, colliding with one another and producing new baby Darumas.
Those baby Darumas eventually mature, increasing the population inside the facility.
But you are not simply watching it all happen.
Using your limited funds, you place one item in each chamber to shape and control the experimental environment.
For example, you might place a piggy bank to generate more money, a hospital to prioritize disease control, a microscope to speed up growth, or a stove or fan to manipulate the room temperature.
What you place, and where you place it, dramatically changes both how the system grows and how it falls apart.
In other words, the player must constantly make decisions with mouse-only controls:
where to expand with new chambers
which Darumas to place, and how many
which item to place in each chamber
which connections to open, and which to block
whether to keep pushing forward, or escape now
This is a game of nonstop observation, management, and decision-making under pressure.
More Darumas does not mean more stability.
As density rises, the risks of disease and corruption increase, while changes in room temperature can also raise the chances of infection and fire.
The player must constantly read the information on the game screen and respond to each situation as it unfolds.
A snowfall warning appears.
The temperature starts to drop.
More infected Darumas are beginning to spread.
Some chambers have already been damaged by fire, and the next lightning warning is on the way.
You might still be able to earn more.
Or this might be the exact moment you need to escape.
Observation and retreat decisions are essential.
Before the game ends in total failure, you can press the Escape button in the lower-right corner of the screen to attempt to leave the experiment site.
However, pressing it does not end the run immediately.
Once you hit the button, a departure countdown begins, and you can no longer interact with the game for a set amount of time.
All you can do is watch and hope the facility survives long enough for you to get out safely.
If you escape successfully, you can bring home the mysterious energy you collected.
The longer you stay, the higher the Chaos Multiplier rises, increasing the value of what you take back.
But if you get too greedy, the entire population may die during the escape countdown, and you lose everything.
You must do both:
know when the run is most profitable, and recognize the signs of collapse before it is too late.
The mysterious energy you bring back can be used in the World Turbine.
There, you can permanently unlock new facilities and systems to prepare for the next experiment.
Each successful escape also updates the Observation Log, gradually revealing more of the world’s underlying rules.
What the player reads is not a story.
It is a record of how this world breaks, what triggers each chain reaction, and when to cut your losses.
The title is Daruma Observation Log, but what you truly need to observe is not the individual Darumas.
It is the structure of the world itself.
Place chambers, then add Red Darumas and Blue Darumas.
They move on their own, collide, reproduce, grow, and eventually disappear.
As you watch these systems unfold, you expand the layout, adjust placements, and build facilities to influence the overall behavior of the experiment.
Controls are entirely mouse-based.
Place Darumas, expand with new chambers, choose and place items, control movement with filters, and press the Escape button when it is time to leave.
The actions themselves are simple, but the decisions behind them are anything but.
Snow, lightning, disease, fire, and violent gusts.
As time passes, risks stack on top of each other and the environment deteriorates at an accelerating pace.
The longer you stay, the greater the rewards become—but the closer you move toward collapse.
