Basically, a playertype that has its camera to the side, and if possible, sticks to that angle the whole time. I don't really mind if that is not possible though, I am happy enough with the camera facing one side of the head... so:
1st person = normal 2D view, the player in the middle of the screen.
3rd person = still 2D, but the camera is further away from the player making the player walk on the edge of your screen, so you can see upcoming dangers ahead.
If someone comes around to making this playertype, please add two different kinds: no jets, and jets. I don't mind if you will like to keep it as a privet add-on for any reason as long as I have it myself.
