Rotate scene or camera with unity 2d physics

I am creating a 2.5d game using Corgi engine with 2d physics., I want my player to rotate along y axis and move then on axis zy instead of xy. I don't know how to do that in unity so the only solution I come up was to rotate all the scene but I think that there has to be a better option than that cumbersome one. Does anybody know how can I do it?
