An experimental 2D Game Engine with Ruby as its scripting language.
You must have MRuby, SDL2, SDL2_ttf, and SDL2_img installed to build.
Building is simple.
Simply create a build directory in the root directory of the project, cd into it, and type cmake ...
This will generate a Makefile you can execute with make.
CMake is able to generate many other project files as well. Check here for more information.
