About
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.

[h2]なぜだるまなのか…なぜだるまの培養なのか…なぜだるまに災難が降りかかるのか…それはなぞのまま…[/h2] だるまを増やす時間とともに、雪に突風、火事に地震、治安悪化病気蔓延にさらされる。 対処の方策は、稼いだ「不思議なエネルギー」で入手する各種機能。 だるまを増やし、部屋をつなげ、各機能を設置し、災難への予防と対処を施していく。 実際のプレイは結構なスピード感で進みサクサク楽しめる。機能追加で延命できるが、その効果を上回る「理不尽」が降りかかるため、コツやパターンを少しずつ理解していくことになる。そこにやめられない止まらない面白さがある。 紹介文には「エモさゼロ、癒やしゼロ、可愛さゼロ」とあるが、苦労の末に増えただるまに愛着を感じ、そんなだるまが雷で一撃されて心に涙を流し、何も起こらない平和な時の流れにホッとする…十分に人間臭い感情を得られる一作。ただ、やっぱり、ヒリヒリ感はしっかりある!
安定したかな?と思った瞬間、あっという間に崩壊が始まるので、非常に緊張感があります。 1プレイはそこまで時間がかかりませんが、あー、もう一回挑戦だ、みたいなやりごたえがあります。
ビジュアル、ゲーム内容ともに高い品質で、プレイアブルな作品。 密度を様々な要素で表現しているのが斬新。 一見単純なシュミレーションルールに見えるが、予想外のイベントやアイテムなどの工夫を施すことで、新たなゲーム性を生み出した新ジャンルのゲームといっても過言ではない。 動画を見て面白そうと感じたら買い。 このコメントを見た開発者さんへ バグ修正ありがとうございました🙇 無事クリアできました。 避雷針を置き続けるなどのマウスの往復操作がかなり要求されるので、アイテムやフィルタなどにショートカットか代替要素がほしい (プレイヤーの操作をある種のコストとして作っている、またプレイスタイルに問題があればスルーしてください) だるまの状態を詳細に見たい(免疫、教育など) よりハードな制約や周回要素があると嬉しいです。
他に類を見ないゲームルール。適度に難しい難易度、工夫すれば確実に成績が好転する仕組み。そして工夫が見事にハマったときの爆発するような手応え。なぜかのダルマも独特な世界観も含め、一朝一夕では作り出せない熟練度を感じさせる。悪者をやっつけるゲームの合間に、緊張感をほぐすためにも最適!ダルマ増やしたくない?増やしたいよねダルマ!インディゲームの個性爆発を見事に再現した一品!夕方のお惣菜を1品、ダルマに買えちゃいなよベイビー!
バイバイ人類。
不思議な世界でだるまを増やしていくゲーム。 なぜだるまかは不明ですが、ゲーム性としてはスピード感のある街つく系、といった感じ。 おそらくはシャーレをイメージした円を組み合わせて、だるまの生存領域を作っていきますが、悪しきものが伝染しないように配置していくのが一つの攻略ポイントで、やってみると結構奥が深い。 ある程度進んだ後の破滅の美学的なものもあり、好きな人には刺さるゲームではないかと思います。 どこであきらめて終了(Escape)ボタンを押すかの駆け引きに慣れると、かなり面白くなると思いますので、最初はどんどん押していくのがおすすめです。
シャーレの中でだるまを育成してポイントを稼ぐローグライト?ゲーム 。UIがとても美しい 結構くせになりそう 青と赤のだるまがぶつかれば子供が生まれて、子供は成長すると青か赤のだるまになる。それで自然増殖をしていくとポイントがもらえる。極悪だるまがマジで厄介でシャーレを破壊してくる難敵 全滅する前に帰還ボタンを押さないとポイントは消失するのでご注意
帰る時の音楽が良い
ハイスピードな街づくり、指数的に爆発するカオス、気温・資金・人口(だるま)・面積などのリソース管理が短いプレイ時間に凝縮されていてとても面白いです。 制御不能に見えて不思議と失敗にも納得感を感じます。結構奥が深いのではないでしょうか。 まだ始めたばかりで10分も生き残れないですが、体感的にとても長く充実した10分になります。
シュールで新感覚!
