The Island where Urso lives is an amazing place with colorful landscapes and a unique atmosphere. It is divided into several sections, which become accessible as the player progresses. Each section has its own unique theme and offers customization slots where the player can place found items.
Good examples of items for customizing the island could be: trees, buildings, statues, fountains, musical instruments, and light installations.
The player discovers new Island customization during their travels, either in chests or by purchasing them in the Shop.
Each customization slot has its own list of items, and each item can only be placed in one Slot. This allows the player to individually decorate each part of the Island, making it unique and reflective of their style.
As Urso embarks on their Journey, it explore the world, filling up a special progress bar. When the progress bar is completely filled, a new section of the island is unlocked.
