AI Inspiration WorldWhat it is
Castle Courier is a 3D browser game by nnour (itch.io account CFrog25). You play the royal raven, carrying letters between seven castles mediating between the realm's fantasy wars and riding out storms along the way. The author says Claude Code (Claude Opus 5.5) wrote the code with Three.js, and the 3D terrain, effects, shaders, bell chimes and storm sounds are all generated in code. The author also mentions making music with Suno but notes it isn't in the game.
Who it's for: Players who like free flight through a 3D world and an easygoing delivery run.
Before you start: It plays free in the browser. On phones you drag and tap FLAP, and on computers you use the keyboard, according to the author. The title is in English; the full language list, age rating and whether results are recorded online aren't stated. Based on the game page's public information. Not tested by AI Inspiration World.
