Brux Game Engine

Introduction

Brux (formerly known as XYG) is an open-source, cross-platform, runtime-based game development kit using the Squirrel language. The aim is to make development both easy and versatile, allowing games to be written by hand in a simple text editor or made in an IDE similar to Game Maker, and to allow games to be ported with little to no modification to the code, offering a "build once, run everywhere" development process.

Developers using Brux may freely make games without any need for paid license or royalties. Anyone willing to donate may visit my Patreon or my Ko-Fi.
