The way later Animal Crossing titles have scrolled make it appear to the player that the game world is round. Zoom the camera out past the confines of a DS/3DS/TV screen, though, and the world is not so much round as it is a giant, habitable roll of toilet paper.
The gif above is taken from this video by Shesez, which breaks the camera off from its usual position and zooms it all over Animal Crossing, taking a look at objects and views we don’t normally get to see of the game.
I love that Nintendo were ready for this in the car and office in a way that is very Nintendo.
