Games do not need pairing with your PC. These are development APKs, not Play Store releases. This page may require your ChatGPT sign-in, depending on its sharing settings. Package details identify the exact retained build; a source rebrand does not change an older APK.
BEHIND THE WORLDS
A place to create.
Our Asset Studio develops an original visual idea into a 3D construction study, with progress, review and export. Our asset viewer lets us inspect real models and animation.
Asset Studio companion & downloadsThe companion requires a paired PC. Install the current companion and use a fresh pairing bundle from your PC for the UJoyK address.
Original assets. Reviewed results.
We author our game art and sound, keep their source files, and review what actually runs. Reconstruction prototypes have their own quality limits; completing a process does not establish premium quality.
02Tools that grow with the games.
Reusable production skills, a 3D asset library and engine experiments live alongside the games. Current game builds use Godot; tools and dependencies retain their own licenses.
ABOUT UJOYK
Built around the joy of play.
Founded and owned by Uri Kahana (UK).
UJoyK is an independent game studio in development. We are creating original Android games, characters, environments and sound — and the tools to keep making them better. U and K carry the founder’s initials; Joy is at the heart of the name.
