From the README

A browser-based 3D scene editor and game engine built on Three.js. Build a scene with a real transform gizmo, give objects physics and scripts, press Play, and export a playable HTML file.

No build step and no install: Three.js is vendored under lib/, so the whole thing runs as static files on GitHub Pages.

One panel per job, docked in two columns. Click a panel's header to collapse or expand it (remembered between visits), drag the header to float the panel anywhere, and double-click a floating panel's header to dock it again.
