Spores–a new, sentient species of fungi–have evolved more intelligent than their rooted ancestors. The rest of the world, however, has evolved too. The Spore colony needs guidance to explore, overcome, and multiply across the exotic world they've bloomed into, lest they become nutrients for this dangerous ecosystem.
In this Roguelite Pet-Simulator, explore runs as the creatures you've grown! When safe at the home colony, upgrade and grow new subspecies to train and nurture. Unlock new furniture and decor to evolve your home, and boost colony happiness.
Choose a Spore from your community to play as, and use their customized stats and abilities to engage in fast, third-person combat against an evolving insect ecosystem. Brave the wilds and bring back as many nutrients as possible to nourish your colony.
Experiment with a variety of weapons, each with their own unique attributes. Scavenge for plant, stone, and bone weapons fashioned from the environment. The farther you adventure, the stronger you'll become!
In the wake of humanity and Anthropocene life, insects, arthropods, and all things that scuttle evolved into vacant ecological niches. The Spores, plump with nutritious fungi, challenge the bugs for the top spot in the food chain. Fight your way through 3 lush, procedurally-assembled biomes, each presenting greater threats but yielding even greater rewards!
