Detailed Description

Base Engine Library

This is just another Sprite Engine library written in c++.

It uses SDL2 for Rendering and is intended to be compatible with Emscripten. source code.

Games written with this library should be able be compiled to other languagges like Javascript via Emscripten(CLANG/LLVM)
