What is Dgame?
Dgame is a 2D framework which is based on the SDL and OpenGL, and is designed for the D programming language. The design is based on Pygame and as well on the SFML from the C++ programming language.
What is special about Dgame?
Currently D has only a few frameworks for games and most of them are C/C++ bindings.
Of those Derelict is probably the most famous and provides support for multiple C/C++ libraries.
Dgame also uses Derelict to access the functionality of the SDL and OpenGL, but, unlike other bindings, Dgame is object-oriented (like the SFML or Pygame) and the only one which is completely written in D.
