The game is 2d and overhead. The player can walk around and scroll the map arbitrarily. (practically the cardinal and ordinal directions, via arrows or WASD)
It's easy to do this if the world, logically is a torus. But if it's a sphere it seems more complex.
I've found resources aimed at representing a spherical world in a 3D game, but since this is 2d and directly overhead.
Is there any way to do this without having to represent the world as a real sphere and then sliding around on it with some sort of square subset of it? And it seems like even this would run into some issues along the edges and really throughout the whole square slice that gets more stretched the further you are from the center of the screen.
