About this 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 an…
