What it is
The Little Prince: Among the Stars turns Antoine de Saint-Exupéry's 1943 novella into a 3D story game you play in the browser. Instead of reading the prince's journey, you travel it: a hand-drawn journey map lays out the planets chapter by chapter, starting on Asteroid B-612, home of the rose.
The creator says each planet from the book became its own 3D scene to explore.
