The Neeblarium is a calm, living simulation about cultivating tiny digital creatures called Neeblies and deciding what’s worth preserving. You don’t control Neeblies directly. You shape conditions, observe what emerges, and intervene only when it matters. Over time, families form. Lineages diverge. Rare traits appear. Some discoveries are fleeting. Others are worth saving. Use your Lab to capture traits you’ve discovered and reintroduce them as new founders. Run multiple biomes as experiments, each telling its own quiet evolutionary story. The world keeps moving whether you act or not. An artificial life sim about attention, care, and making something last. Your role in The Neeblarium: Establish conditions for life within a running ecosystem Introduce eggs and observe Neeblies grow, adapt, and reproduce on their own Watch families form and lineages diverge across generations Notice mutations, rare traits, and subtle behavioral differences as they emerge naturally Use a Lab to preserve discovered traits and reintroduce them as new founders Run multiple biomes in parallel, each evolving independently over time Decide when to intervene, curate, or simply let things run Your choices shape long-term outcomes, but the system never demands constant micromanagement. You can be hands-on, or almost completely hands-off. The simulation doesn’t demand constant input — but it does reward attention.
