Meh2D is a simple game library based upon Allegro 5 to easily realize 2d games in C++.
The API documentation could be find here : http://remeh.fr/meh2d-api/
I'll add some tutorials on the wiki and link to a game realized with Meh2D for the Ludum Dare, but as of today, you can take a look at the examples provided with the sources.
