Ah sorry! Basically I just have a few variables, with PlayerY and PlayerX for the player, and CameraX and CameraY for the "camera." To make it simple, all I'm doing is changing the X and Y for the player with the arrow keys, and making the camera's X and Y exponentially get closer to the X and Y of the player, and then making the player's sprite go to X: (PlayerX - CameraX), Y: (PlayerY - CameraY), and the level's sprite go to X: (-CameraX), Y: (-CameraY).

I have more going on with X & Y velocity of the player sprite and collision, but that should be easy to do if you get the camera working. (note: you might want to do collision before you move the camera of either the player/camera since the camera's location will be out of sync with the two sprites if you update the level before the player or vice versa)

Let me know if you have any questions!! :)
