Umm 5anz... That is just flat out wrong. ๐ญ๐
The first dimension LITERALLY IS the x-axis. The x-axis doesn't go up and down. The 1st dimension is a space with only one direction: length.
For the 2D game, it doesn't matter if it's a top-view or side-view. It's still on the x-axis and y-axis: length and width.
