The primary objective was to port the library from allegro to Raylib, but many other features were implemented on the way. * Converted the old code, and rebuild the engine with Raylib (since the logic is different) * Converted some of the old unit test and generated new ones. * I redefined the internal structure of the maze file, its now bigger * I designed the geometric calculation to allow different configurations and put them a place it makes sense. * I implemented animations using different number of frames changing speed and smoothness of animations * I added slopes which allows moving up and down in the maze without requiring any user interface. * I implemented chasm and open ceilings. * The Keyboard has be implemented left and right handed, while the joystick is also supported. * Various situation can trigger events which can be intercepted by the game. * Implemented cubes and quad buffers to separate the projection room building from the geometry to make it easier to test.
