So I stumbled upon a video of how it’s like to live in a 2D world where you all you would is lines and you can only see from your sides technically speaking. I think I have a grasp of how a 3d world works when it comes to moving around. So how does one move in 4D world?

I think I’ve seen that video. The emphasis of it been that a person living in a 2D world cannot conceive of a 3rd dimension (as they’d have no concept of depth), and so person living from a 3D perspective would find it difficult to conceive a 4th dimension perspective.
Even if you choose to label time as the 4th dimension, an aspect of the above is being able to see multiple points of a lower dimension simultaneously.
