How the game teaches without words
Foundation — Simple concepts, generous timers, forgiving encounters. Player learns the core loop: explore → encode → recall.
Challenge — Competitive encounter introduces stakes. Concepts require distinguishing subtle differences (over vs. underfitting).
Complexity — Multi-step recall. Concept ordering matters. Slower pacing rewards careful thought over speed.
Mastery — Cross-island recall. Everything connects. Ethical concepts ask "should we?" not just "how does it work?"
