Fun Builds
SPARK
A kids' venture-sim game built for our own family: children direct an AI orchestra to build pretend businesses, inside the strictest safety architecture in this portfolio.
01 The story
Some builds are just for the family. SPARK is a cozy, non-combat venture simulator where kids play founder: they direct an AI called The Orchestra, watch the market react, and grow a companion coach named Lumi through five forms, but only by developing balanced skills. The safety architecture is stricter than anything else here because it has to be: parental consent and time caps, ephemeral voice, no training on child data, mandatory breaks that gate play sessions, and a coach that is deliberately a tool, never a friend, and routes any emotional disclosure to a real adult.
02 What went into it
- Non-combat venture sim: founder moves in, market reactions out
- Lumi coach with five balance-enforced evolution tiers
- COPPA-by-design: consent, time caps, ephemeral voice, no child-data training
- Anti-dependency mechanics: hard daily caps and mandatory breaks
- Zero-server on-device taste mode for pre-consent play
- Accessibility as a launch requirement: read-aloud, captions, dyslexia-friendly type
03 Claude in production
Every AI call runs server-side under the Lumen governance layer: no client keys, cost telemetry on every call, and a human confirming every consequential write.
