The core principle of the game OSMOSE recreated in HTML/Javascript in a vibe coding playground.
An orbital mechanics game where you control a celestial body orbiting a sun. Eject mass to maneuver, absorb other bodies to grow, and eventually consume the sun itself to become the new gravitational center.
Open orbital.html or the all-in-one standalone build at dist/orbital-mono.html in a browser.
Controls:
- Click to eject tiny mass amounts toward cursor to proell yourself (repeat faster clicks to eject more mass for more recoil – conservation of momentum)
- Scroll to zoom in and out
- Hold Space to speed up time
Modular architecture with separated concerns. See ARCHITECTURE.md for the full structure.
Build monolithic version:
node _build/assemble.js- Pure HTML5 Canvas
- Vanilla JavaScript (no frameworks)
- Procedural generation (simplex noise, FBM)
- Keplerian orbit mechanics with simplified/gemoetric/2D mass gravity system
