4th Dimension
The mathematical extension of the concept of 3D space and the limit to the observable universe.
Width. Another Line.
The Second Dimension builds upon the first by adding width to length, creating a plane where objects ecist with area but no depth. It's a flat world of shapes and surfaces, fundamental geometry, physics, and our understanding of higher dimensions.
Navigation. Flat Architecture.
Similar to a sheet of paper or a computer screen, the 2nd dimension is infinitly thin with only horizontal and vertical movement possible. Shapes like circles, squares, and triangles exist here. 2D video games like Teraria and Hollow Knight exemplify these atributes, allowing players to navigate only with whats diretly in front of them, with no consideration for depth.
