Observation Daruma Log

About the Game

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.

What You Do

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.

It’s Not Just About Growing More

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.

Escape, or Get Greedy

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.

Through Repetition, the Structure of the World Reveals Itself

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.

Features

■ Place Darumas, Observe Their Growth, and Operate the Facility

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.

■ Mouse-Only Decisions: Placement and Retreat

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.

■ A Roguelite That Falls Apart Through Disaster

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.
