About the game
Step into a summer that never ends.
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⊠thereâs a tiny world waiting.

You play as 11-year-old Jenny, a bright and energetic resident of the terrarium.
But this isnât just her story.
Somewhere, buried deep under the summer days and small-town routines, is another life.
Unravel the mysteries of the terrarium.
Beneath the nostalgic atmosphere of this close-knit town lies a hidden truth. Explore a âperfectâ pocket world to reveal its secrets and progress through a non-linear narrative shaped by your choices.

Meet dear friends youâve always needed.
Jennyâs 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
Live your days as dreams.
Days in Vivarium are synced to the playerâs 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 tomorrowâs adventure
Sprout quickly, little treeâŠ
but can this small world contain you?
