Sprites and Platforming?

Hello all. I'm using Spritemanager2 in my game, I'm attempting to build a basic platformer using sprite characters.

Sadly, there isn't a lot of documentation surrounding sprites as far as Unity is concerned. How to move them, how to set up collisions, etc. Could anyone point me to a resource on how to work with sprites inside Unity? Or perhaps a basic platforming tutorial? Or at the very least some tips on how to get started?

Use a flat plane with a texture on the side, and turn it to face the camera (which should be orthographic). Give the plane a parent box collider object/ character controller for collisons. Just think of 3d, but with billboards rather than meshes.
