Indie games often come with a story, but Zefyr: A Thief’s Melody is a tale all its own. Developed over the course of 12 years by solo French dev Mathias Fontmarty of Oneiric Worlds, this vibrant stealth-adventure game is finally making its long-awaited debut on Steam and itch.io on June 2, 2025.
Brimming with heart, colorful visuals, and nostalgic throwbacks to PS2 and GameCube classics, Zefyr: A Thief’s Melody is a meditative, feel-good journey across a dreamy archipelago. If you’ve been craving the charm of games like The Legend of Zelda: Wind Waker, Sly Cooper, and Beyond Good & Evil, this one’s for you.

What is Zefyr: A Thief’s Melody?
Set across a colorful ocean world, Zefyr casts you as Eïko, a young thief-in-training who finds herself wrapped in a mysterious plot involving kidnappings, pirates, and ancient guardians. Players can choose stealth or action to complete missions, but the real joy lies in free exploration: climbing sheer cliffs, gliding from high peaks, sneaking through enemy camps—or just cruising across the sea on the back of a giant, friendly turtle.
It’s a joyful blend of puzzle-solving, heartfelt storytelling, and whimsical world design that aims to be as therapeutic as it is fun.
🗺️ Explore a Living, Breathing Archipelago
From lush forests to pirate-infested coves, Zefyr encourages players to take their time and enjoy the scenery. Climb, glide, or turtle-ride your way through a rich, open world filled with:
- Secret caves and hidden paths
- Peaceful villages and quirky characters
- Side quests that reward curiosity
- Animals to heal and rare items to collect
The game’s lack of fall damage and its generous climbing mechanics make traversal feel liberating rather than punishing.
🥷 Choose Your Playstyle: Stealth, Combat, or Both
Each mission offers multiple approaches. Knock out unsuspecting pirates, sneak past robotic guards, or go in with a staff and slingshot blazing. Strategic players can use the environment to their advantage, while explorers may find ways to skip conflict entirely.
🧩 Puzzles, Kidnappings, and Clues
Beyond combat, the narrative drives you to investigate a growing number of disappearances. Talk to locals, follow leads, and solve puzzles that test both logic and observation. It’s a story of mystery and healing, centered on bringing balance back to a world on the brink.
🐢 Features That Set Zefyr Apart

🎨 From One Man’s Dream to a 12-Year Reality
Mathias Fontmarty, the one-man team behind Oneiric Worlds, poured over a decade into Zefyr—coding, drawing, animating, composing, and designing solo.
“This is the kind of game I would have loved as a kid,” says Fontmarty. “It’s full of joy, light exploration, and whimsical characters—meant to make you feel good while inviting you to think and discover.”
