Sky Isles

The ancient tree isle

What Sky Isles is

A small exploration game in a pastel world. You walk a little character across nine islands that float at different heights, linked by five rope bridges and three glowing mushroom jump pads.

Five wind chimes hang on five of the islands. The mural on the home isle paints their order: sun, leaf, moon, wave, star. Ring them in that order and a portal opens to a quiet star isle. Ring one out of order and the song starts again.

• 9 floating islands
• 5 wind chimes
• 5 rope bridges
• 3 jump pads

On a keyboard you move with WASD or the arrow keys, jump with Space (twice for a double jump, hold it to glide on the cape) and ring a chime with E. On a phone there is a joystick and a jump button.

How it was built

Sky Isles is JavaScript on Three.js 0.179, built with Vite and drawn with WebGL. Every island, bridge and chime is built in code from simple shapes, and every texture, from the cloud puffs to the murals, is painted onto a canvas when the game loads. It downloads no 3D model files and no sound files.

• The soft cartoon look is toon shading, with a dark lavender outline drawn as a second, inside-out shell around each shape.
• The light shafts are see-through shapes angled from the sun, and the sea of clouds is an endless cloud layer with drifting puffs on top.
• The music is made live with the Web Audio API. Each chime plays its own note of a pentatonic scale, and every chime you unlock adds one more instrument to the score.
• Movement, the chime puzzle and the seeded random generator are plain logic with 19 unit tests, and Playwright plays the game in a desktop browser and an iPhone-sized one.

What it shows about how we build

A game has nothing to hide behind. It has to feel right on the first tap, on a phone and on a desktop, or the visitor is gone.

So the rules (how the character jumps, falls and glides, what a wrong chime does) live in small modules that are tested on their own, the look is held to a written art direction, and the finished game is played by a test in a real browser before it ships. That is the way we build business software too: the rules first, proven on their own, then the screen on top.
