Across the Mushroom Kingdom
World 1 opens on grassy plains; World 2 moves into the desert; World 3 explores coastal and water stages. World 4 is a forest route, World 5 brings snow, World 6 climbs rocky terrain, World 7 heads into the clouds, and World 8 ends amid lava and castles.
Branching paths
Worlds 4 and 7 are optional branches unlocked through Mini-form boss victories. Red secret-exit flags can open alternate paths, while cannons can skip forward. A normal finish does not reveal every route.
Read the map after a new exit
When a level produces an unexpected route, return to the map and inspect what opened before immediately selecting the next stage. Secret exits can explain why an apparently straightforward sequence has a branch or a missing connection. On a collection visit, choose one unresolved route and keep the needed power-up in mind. This makes world exploration more deliberate than replaying every level without knowing what result you are seeking.
