What the developer says
This game contains AI-generated content that was created during development and ships as fixed files. Nothing is generated while you play. - Images: card paintings, menu and loading paintings, and some textures were generated with AI image tools, then edited, painted over and composited by hand. - 3D: some character and prop parts began as AI-generated meshes and were rebuilt, cleaned up, rigged and textured by hand in Blender. - Voice: the character voices and their dubs in six languages were generated with ElevenLabs from scripts written for the game. - Music: the score was generated with ElevenLabs Music and Suno from briefs written for each scene and character. - Sound: many sound effects were generated with ElevenLabs and edited and layered with recorded sound libraries. - Text: story, interface text and translations were drafted with AI assistance, then reviewed and edited by the developer. Game design, rules, the rivals' behaviour, the castle and table layout, and the final say on every asset are the developer's own. The rivals do not use generative AI: they play by hand-built logic and cannot see your hidden card.

| AI judgment deepseek-flash | Major AI · mixed signals, high confidenceReasoningThe disclosure lists AI generation across most asset types: images, 3D meshes, voice, music, sound, and text drafting. That covers several major categories, so scope is major rather than parts. Hand editing, custom scripts, and hand-built game logic show real development effort, keeping effort risk medium. Against: The developer reports hand painting, rebuilding meshes in Blender, layering recorded sounds, and writing original scripts; game design and rival logic are hand-built, and only one game was released in the last 12 months. |
