Understanding the Game Structure
The game is divided into three core layers:
- Main Island Quests – storyline missions that advance the island's restoration.
- Side Quests & Mini‑Games – optional tasks that provide extra resources and decorations.
- Collectibles & Achievements – items such as shells, stickers, and costumes that unlock bonus content.
Each layer has its own progress bar, and the game only lets you finish when every bar is full.
