You begin as a tiny swimmer in a busy reef, surrounded by creatures both harmless and hungry. The rule is simple but never static: eat what’s smaller, avoid what’s larger, and your own size and confidence increase with every safe bite. Movement is snappy and precise, so a good line through traffic can turn a risky screen into a feast. The moment you cross a size threshold, new targets become edible and yesterday’s threats start looking manageable. Rounds are brisk, but each one leaves you reading the crowd of fins a little better.
