Porta Nubi for iPhone Duo - Press Release
Independent developer Michael Temper brings his immersive light puzzle game from Apple Vision Pro to iPhone Duo, where folding and unfolding the device becomes part of the gameplay. The game will also be available on iPhone and iPad.
On October 23, 2026, the immersive puzzle game Porta Nubi arrives on iPhone Duo. Originally designed for Apple Vision Pro, the game has been rebuilt around the foldable iPhone: closing the device dives the player into a cloud, opening it pulls them back out. Every pose of iPhone Duo, from Laptop to Book, gets its own tailored experience.
Porta Nubi is free to download from the App Store, with opKonal in-app purchases for addiKonal chapters. It runs on any iPhone and iPad with iOS 27.0 or later, but iPhone Duo is where it truly unfolds.
Built for iPhone Duo
Porta Nubi treats the folding hinge as a game controller. Instead of simply stretching the interface across a larger screen, the game reacts to how the player holds the device:
- Fold to dive in: Closing the phone jumps the player into the most centered cloud on screen.
- Laptop pose, instant gamepad: When iPhone Duo is set up in Laptop pose, a virtual gamepad appears automaKcally on the lower half, while the clouds fill the upper half.
- Book pose, adapMve tutorial: Held like a book, the game shows an adapKve tutorial alongside the puzzle, so new players learn each mechanic as they play.
- At home in every pose: NaKve Toolbar Items and a Tab bar give Porta Nubi an opKmized layout in every pose, so it feels like a natural part of the system.
Porta Nubi: Light puzzles among the clouds
The rules are simple. One or more sources emit light, and the player must guide each beam to its matching target. Mirrors, portals, light prisms and moving elements make this increasingly tricky.
The main obstacle is the clouds themselves, which block the light. Players can cut holes into them to let straight beams pass through. The catch: the correct path can lead in any direcKon. To redirect the light, players shrink themselves into a cloud through one of the holes they cut. Inside, they control portals that catch the beam and send it onward.
The name comes from LaKn: "porta" means gate and "nubi" refers to clouds, making Porta Nubi the gate to the clouds.
From Apple Vision Pro to the palm of your hand
Porta Nubi first launched on Apple Vision Pro on May 27, 2025, where players used their own hands to cut through clouds and catch beams of light. The game quickly appeared among the App Store's best Apple Vision Pro games and went on to win the App Store Award for Apple Vision Pro Game of the Year 2025.
The iPhone Duo version carries that same idea, making the player part of the game, onto a device that fits in a pocket. Instead of reaching into the clouds with their hands, players now fold their phone to step inside them.
