I agree with Martin, a re-watch is a good idea, even more so it’s to start from scratch. When things start feeling too complex, it’s always best to take a step back. When re-watching you’ll get more speed and after making the mistakes, the solutions will appear much more obvious. Also remember Press Start is not so beginner friendly, there’s always the Blender Basics for that:
