Kindness Circuit

Kindness Circuit: a cozy mobile run. Jump to keep Water/Food up, grab drone-dropped stones for score, clear rounds as drops speed up, reset on mistakes, and climb the leaderboard. GenAI-built.

Inspiration

We wanted a non-violent, mobile-first game loop that still feels intense. “What if score came from kindness choices instead of weapons?” That became Kindness Circuit—a single cyclic track where jumping for Water/Food keeps you alive and color stones shape your glow and score.

What it does

You spawn on a looped track. Water (−0.5/s) and Food (−0.25/s) drain as you move—jump to collect orbs. Overhead drones drop stones (White/Gold/Green/Blue good; Red/Black/Fire risky). Clear the Start→End round, then drops speed up next round. Fail by falling into the ocean or reaching the gate without enough stones. A leaderboard tracks Round • Time • Score.

How we built it

Engine: Meta Horizon Worlds Desktop Editor (mobile-focused).

APIs: horizon/core (events, entities, storage), horizon/ui, horizon/camera (micro zooms).

Systems: Start/End triggers, RoundManager (escalation), Dropper (stone table, SFX/VFX), PlayerStats (drain, fail/reset), Leaderboard (Round/Time/Score).

Design: diegetic bars + Aura ring feedback; Sanctuary Ghost VO with short reactive lines.(With bugs)

GenAI: ~80% of code drafted with GenAI and refined by us; 100% of assets (3D models, skybox, textures, SFX, ambient audio, environment generation) created with GenAI tools permitted by the rules; all reviewed/edited, licensed, and optimized for mobile.

Challenges we ran into

Networking/ownership: server/host authority for pickups/round timing; anti-double-collect cooldowns. Asset budgets: emissive trims, low-tri meshes, limited overdraw for stable mobile fps

Accomplishments that we're proud of

  • A 2–5 minute loop that’s fun in the first 20 seconds.
  • Clear, non-violent risk/reward that players grasp instantly.
  • Robust Round/Dropper/Stats stack with resets and clean feedback.
  • Leaderboard that drives replay.
  • Cohesive art+audio style generated with GenAI and polished for Horizon mobile.

What we learned

  • GenAI excels as a co-creator—but human curation is essential for polish and performance.
  • Worlds Desktop Editor expertise

What's next for Kindness Circuit

  • Adding more enhancements and bug fixes
