Resources for learning to create a simple game engine

[tristthefist117]

I know this question has been asked similarly before, but the answers were not satisfactory.

I'm a beginner c++ programmer, and want to develop my programming skills immensely.

To do this I want to create a very simple 2D game engine, an engine that will effectively render a game similar to 'the worlds hardest game':

though what I have in mind is an approach slightly different to a typical game engine, instead of me creating the graphics and design manually, I want all of the levels to be procedural generated(I love no mans sky's approach)

can anyone provide me with resources that I can use to get started? what tutorials are there for making a simple game engine? What should I avoid in order to prevent myself from doing bad habits?

Thanks

P.S
I am deeply familiar with unreal engine 4, though the engine is just too complex, and contains a lot of code that I want to fill in myself

The book called Programming 2D Games. It's very easy to follow and includes a very basic engine with three main components, Graphics, Input and Game, all with full source code and written like a tutorial. In the book he uses the engine to create a space invaders type game though it can be used for any type of game. There's even a section on custom gui widgets like buttons and progress bars. He uses Direct3D for rendering 2D graphics and text. I recommend this because its very easy to get something working after reading it.

However that book doesn't explain more advanced things like procedural generation, scripting, and physics and particles.
