A cozy farming game built as an AI template for creators.
A cozy farming sim for Meta Horizon on phones and the web, built as an AI template for Meta Horizon Worlds: a deliberately simple base that creators grow into their own game by asking Meta AI.

01 — THE PROBLEM
A game designed to be rebuilt by someone else.
Unlike our other projects, the goal wasn’t a finished game. Terrarium is an AI template for Meta Horizon Worlds: a simple, vertical slice with clearly defined places to extend, so creators can turn it into their own game just by asking Meta AI.
02 — THE BUILD
Three decisions that make it easy to extend.

A small, satisfying loop
Four 3×3 plots and three tools: Watering Can, Shears and Seed Bag. Tend plants with a short hold, watch coins roll in, then unlock new plots and upgrade tools.

Everything tunable lives in data
Plant needs, timings and when new plants appear are defined as data, not code, so creators can ask Meta AI to change them, or to add their own progression and goals, without touching the core.

Tested against real prompts
The template ships with documentation and was tested against golden prompts, the reference requests it had to handle, with AI skills that help Meta AI carry them out.
