How can I switch movement on an axis with a paper 2d character

I have successfully made my first paper 2d character and made it move around. However, I can only move up and down on the Y axis and left and right on the X axis.

Sometimes I need to have the camera change perspective, and I cannot figure out how to make the paper character move up and down on the X, or left and right on the Y. Anyone know how to do this?
