The core of the game

Send it on the tide

Your part is simple: choose what goes in each crate and send it out on the tide. Everyday odds and ends wash up on his beach, and Milo figures out what they’re good for on his own.

  • 👗 A summer dress→a fishing net
  • ⛸️ Hockey skates→a hand axe
  • ☂️ An umbrella→a rain catcher

What you send shapes how his island grows. Some ideas come to him right away. Others he figures out days later, and once he’s learned something, he remembers it.

A little life of his own

He learns. He adapts.

Every useful thing Milo figures out stays with him. Over time he builds habits, quirks and routines of his own, so no two castaways turn out the same.

🎣

Routines

He fishes at dawn, naps in the afternoon heat, and lights his fire at sunset.

🧠

Personality

He hates thunderstorms, loves the north beach, and has started carving little wooden figures.

🌱

Gentle by design

Milo never dies and there’s no game over. While you’re away he looks after himself, just at a calmer, slower pace. It’s a place to relax, not a chore.

Weather that lives

Storms roll in and rattle the thatch, and Milo patches it up. Calm seas bring slow tides. Rough seas wash up bonus crates. And his island follows your clock: morning when you're starting work, a glowing campfire when you're up late.
