It is a P.O.C. of a 2D game made in C++ with GCC compiler and SDL2 libs.
No one engine was used to create this. The sprites, tilesets and some linear pixels was coded and using SDL as a renderer.
If you are using Debian linux, install the SDL2 libs running install-dsl.sh.
On Windows OS, you could install the libs and compile using MinGW.
On the MacOS systems, you can install SDL libs using homebrew.
Just run sh compile.sh, it invokes gcc compiler with the links and after the compilation,
it will execute the bin file.
