A cosy, no-pressure game built for a little one — and shared for anyone who'd like it.
Octavia's Unicorn World started as a game a grandad built for his granddaughter, Octavia. You begin by designing your own unicorn — its colours, its horn, even its name — then set off across a tiny round planet dotted with grass, trees and little lakes. Gallop over the hills, spread your wings and take to the sky, follow the sparkle-arrow to find gems, and curl up for a nap when you're tired. It's deliberately calm and kind: there's no way to fail, no ads, and nothing to buy.
Everything a small explorer needs, and nothing that gets in the way.
Choose the body, mane and tail colours, pick a horn shape and size, type your name, and set an easy or normal difficulty.
A soft, round pastel world with rolling hills, streaming trees and flowers, gentle lakes and a friendly sky to roam freely.
Walk, gallop for a burst of speed, or spread a pair of wings and fly. An energy bar tops back up when you rest.
A gentle guide-arrow points to the nearest gem, warming from yellow to green as you get close. Reach the goal for a cheery well-done.
Pick a cat, puppy or bunny to trot along beside you — and it even curls up to sleep whenever your unicorn does.
Deer, foxes and other friendly animals wander the meadows while butterflies and ladybirds flit around you.
Feeling sleepy? Lie down for a nap to recharge. It's a game you can put down and pick back up whenever you like.
Keyboard, gamepad or touch — on Android you get an on-screen thumb-stick plus Fly, Run and Sleep buttons.
