I remade No Man's Sky with Claude Opus 5.5 + Three.js on Tesana – traverse the galaxy fully seamlessly

A developer recreated a No Man's Sky-inspired game using Claude Opus 5.5 and Three.js on Tesana. This browser-based game allows seamless traversal from planets into space and to other planets without any loading screens. The project was completed in approximately 40 minutes of generation time, demonstrating the capabilities of the tools used.

Unlike other generative AI game demos, this one showcases seamless, continuous traversal from planet to space to planet, a feature often challenging even for traditional game engines.
