The EXT Library is set of various useful classes, templates and macros that extend functionality provided by ISO C++ (ext sub-library), standard C and C++ library (lib), to abstract parts of Windows API (win) and access PE file resources (res).
GWT is an flexible and object-oriented 2d game engine. It uses Code::Blocks and is based on SFML2 to give the ability to port your code to multiple platforms.
With the integrated all-in-one tool for game resources it's possible to develop games in a short time.
And it's open source! (license coming soon)
