I was exploring the internet for 4d space and
object simulations when I found a very interesting site that presents and explains it nicely
But I couldn’t find anywhere mention of what a 4d object projects onto 2d space
Here is the site for anyone interested:

It would also be 2d? How would it cast a 3d shadow onto a 2 dimensional space?

A projection on 2d space (normally called a plane) is necessarily 2 dimensional. Since your computer screen (and eyes, mostly) is 2 dimensional, that website is actually already showing you a 2d projection! Its just that your brain is pretty good at turning 2d projections into 3d objects so it can seem 3d.

A 2D shadow. 2D space can’t have more. You can’t have a 3D object on 2D space, only its shadow. So the 4D object would still cast a 2D shadow into 2D space. Imagine a 3D object casting a shadow into 1D space: the 2D shadow is flat. Remove another dimension and it becomes a line. This would be like casting a shadow onto a piece of paper and then looking at the paper from the side.
