How To Do Basic 2D Movement?

Hey,
I’m making a simple RPG (Just a single map with various stores, where you can buy stuff) and have absolutely no idea how to do 2D movement. I’ve asked a few times on GameDev.net, and have not found solutions that work for 2D games. I did find an online tutorial, but that had ray-tracing a lot of other complicated stuff I couldn’t wrap my head around. Is there a tutorial out there on how to create Risk of Rain-esque movement? The movement is nothing fancy, and the camera is in a consistent location relative to the player. It’s effective and good.
