I found 4D Golf a great game to explore higher dimensional space.

Got a link?

I imagine they are taking about 4D golf by CodeParade, as seen here: https://youtu.be/y53UNskR-zU?si=iUfCkxYqkACx955t

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

		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.
