Building the game logic

We now have all the requirements to start our game: resource management, events management, GUI, animations, map, and the entity system. It's time for us to group them into a single project.

First, we need to create our entities. Thanks to the entity system previously described, we only need to build some components and their systems. We can build many of them, but the main components for the project are as follows:
