How it works
Knowledge, meaning, and play — kept apart on purpose.
Earth Challenge is built on three clean layers. Separating them is what lets one set of facts become a dozen games — and lets the product keep growing without ever rewriting its foundation.
// Layer 02
Meaning
Every group is tagged with what it can become: a sequence, a set of opposites, a category, a tool and its use. This semantic layer is where the intelligence lives.
// Layer 03
Play
Each game mode declares what kind of data it needs. A level is simply one learning group met with one compatible way to play — chosen to fit the child.
