     - [MultiOgarII](https://github.com/joelsgp/MultiOgarII), my fork of a popular free server in node.js for the viral agar.io game – I made some bug fixes and improvements.

     A few help guides, programming opinion, some pretty good research on the retro games stuff. Made in Jekyll for GitHub Pages, so mostly markdown with some custom html, css, js, config files and helper scripts. CC BY-NC-SA 4.0 ([source](https://github.com/joelsgp/joelsgp.github.io/))
