It doesn’t have a GUI editor for tweaking the game contents, like Godot has it, but it’s a complete game engine, so with a tiny bit of configuration, it will do all the things to display your game in a window.
So, it’s not just a graphics library/module, where you’d still have to write a whole structure yourself, but rather a framework, which means it provides a structure for you and you basically just have to fill out the blanks with whatever you want drawn.
