Progression Curve

How the game teaches without words

🟢 Islands 1–2

Foundation — Simple concepts, generous timers, forgiving encounters. Player learns the core loop: explore → encode → recall.

🟡 Island 3

Challenge — Competitive encounter introduces stakes. Concepts require distinguishing subtle differences (over vs. underfitting).

🟠 Island 4

Complexity — Multi-step recall. Concept ordering matters. Slower pacing rewards careful thought over speed.

🔴 Island 5

Mastery — Cross-island recall. Everything connects. Ethical concepts ask "should we?" not just "how does it work?"
