Terrarium Simulator [Alpha 1.0.2]
A Roblox experience owned by KOSMOS Games.
Description (written by the developer; not a statement by this register)
🌿 **Welcome to Terrarium Simulator!** Create and manage your very own living terrarium ecosystem. Place plants, collect creatures, decorate habitats, and balance humidity, comfort, pollution, and biodiversity to build a thriving miniature world. Watch species interact, discover new combinations, and develop a self-sustaining ecosystem. Every creature and plant plays its own role, and your decisions directly affect the health and stability of the terrarium. Terrarium Simulator is developed by an independent creator and is currently in active development. This version is an early MVP, and many new features, creatures, plants, equipment, discoveries, progression systems, and visual improvements are planned for future updates. Thank you for playing and supporting the development of Terrarium Simulator!
