The problem with these attempts always seems to be that you can see in dimensions 1-3, but never in dimension 4, so any movement or exploration along that axis is always just blind fumbling. The extra dimension is not equivalent to the others
The only answer would seem to be an extra axis of rotation, but (a) doesnt work well with existing input methods, and (b) would be even more of a brain-breaker
I just watched the associated dev video And if I understand it, what the author is doing is kind of interesting.
The sensor to see a 3d scene is 2d(eye or camera). What is being done here is simulating a 3d sensor(for a 4d world) then we are looking at this 3d sensor using our 2d sensors (eyes). I don't know if this is the common way of rendering these 4d physics simulations. But it is the first I have heard it described this way. It is also why the narrative of the game focuses on eyes, because that is what it is doing.
Some of the scenes from the video remind me of Manifold Garden [1] - only 3D but a 3-torus [2] and you can change the direction of gravity, i.e. what is up and down. And also visually beautiful.
That's exactly 4D. Just like "non euclidean"[1], this term is often abused in entertainment to mean something else, but the post here is about the real 4d world rendering.

The person goes over quite a few technical details on their Youtube, though they talk about a bunch of other coding experiments too.
