You wake up and find yourself in an enormous terrarium. Explore, meet characters, and grow your escape - and along the way, uncover the mysteries of the terrarium as well. Vivarium is an adventure game about finding where you belong while surviving in a familiar yet alien environment.
You wake up in the golden haze of late afternoon. The air is warm, cicadas hum somewhere in the distance, and sunlight spills across your bedroom.
And outside your window… there’s a tiny world waiting.
You play as 11-year-old Jenny, a bright and energetic resident of the terrarium.
But this isn’t just her story.
Somewhere, buried deep under the summer days and small-town routines, is another life.
Beneath the nostalgic atmosphere of this close-knit town lies a hidden truth. Explore a “perfect” pocket world to reveal its secrets and progress through a non-linear narrative shaped by your choices.
Jenny’s charming neighborhood is inhabited by a charismatic cast of characters, each with their own branching and dynamic storylines:
A reclusive woman slowly becoming something else
A shopkeeper that gives daily album recommendations
A funny postal worker who drinks like a fish, and is a fish
A nosy retiree birdwatcher, who keeps tabs on the other townies
A wandering fortune teller who seems to know too much
Days in Vivarium are synced to the player’s real-world calendar, allowing for daily new discoveries while unraveling its mysterious narrative. Completing major story events will progress time, but every night provides endless slice-of-life comfort and time that can be spent:
Cooking new recipes and tending to your garden
Collecting stickers, vinyl records, and classic novels to enjoy
Crafting items and decorating your cozy home
Repairing equipment and preparing for tomorrow’s adventure
