Worlds

Upon launching the engine, you'll be greeted with a selection of default worlds to load. Each world is physics-enabled, allowing you to walk around, pick objects using your mouse, and even drive a car. These worlds are designed to offer a diverse and enjoyable experience

Interesting facts

This engine started as a way to learn and enrich my portfolio while I was a university student, circa 2014, represeting over a decade of non-stop development.
It's one of the most rewarding projects in terms of the perks you receive should you become a contributor, more here.
