A developer built a 3D *The Little Prince* narrative game in just 16 days using Opus 5.5, allowing players to now step into the planets from the original book.

Beating AI Express: AI creator Sac spent 16 days adapting *The Little Prince* into a browser-based 3D narrative game titled *The Little Prince: Journey of the Stars*. Players can control the Little Prince to visit the king’s palace, traverse the rose garden, meet the fox, and locate the pilot in the desert. Beyond scene displays, the game includes interactive tasks such as watering flowers. According to the creator, Claude Opus 5.5 handled coding and game development; Tripo AI under VAST (Sanqi Wanwu) was used to generate 3D models, Blender for model and scene processing, and Unity to integrate all elements into the final game. Even the promotional video was produced by Opus 5.5 and Blender via a single prompt. The game is now available for free trial, with its official website supporting 8 languages including Chinese, English, and Japanese. However, it still has room for optimization: some players note gameplay is currently centered on scene exploration, with immature jumping mechanics and character animations, while others report performance lags. The web version requires browser WebGPU support, and each chapter needs downloading large resource packs. The creator plans to open-source the entire project and its detailed production process in the future.
