What it is: A casual flying game where you deliver baby animals to their matching moms.

We presented at NYVR (July 2025)! Here are our slides.

Why
  • Horizon’s player base favors playful, snackable loops; a whimsical flight mechanic felt differentiated.
  • Goal: test a simple pick-up and deliver core loop that’s teachable in seconds.

How
  • Flight implementation: the player “wears” the bird; movement is driven by simple physics for stable control.
  • Asset pipeline: fast 2D-to-3D using ChatGPT + Meshy; lightweight 2D HUD and custom leaderboard.
  • Build constraints: in-editor co-editing, auto-multiplayer, cross-device playtests; modular scripts and strict naming to manage world caps.

What
  • Core loop: start at the delivery station, mount the stork, grab a baby package, fly to the right mom, earn a score on the HUD and leaderboard.
  • Extras: a baby-bird “intern” companion follows the player.
  • Stack: Horizon Worlds editor, TypeScript, simple physics helpers, in-world UI.

So What
  • In-app authoring and auto-multiplayer made iteration fast without external networking.
  • Constraints (object/vertex caps, sync quirks) encouraged modular scripting and clear ownership.
  • AI-assisted asset generation materially shortened turnaround without blocking gameplay tests.

Next
  • UX polish: clearer onboarding, richer feedback, and lightweight progress tracking.
  • Art and audio: unified visual language, interactive SFX.
  • Content: new biomes (desert, ocean, polar) and additional animal sets.
