move with the arrow keys move the camera with wasd (don't make him go off the screen, or you'll create an infinite loop :S)a slide the 'scrolling?' things to change whether it is scrolling on the x or y axes, change the 'keys' variable to change whether it bothers to detect keys, and that's basically it. Oh, and there's a costume variable there too. This also shows that you can make sprites that are bigger than 480x360 in 2.0 :D
I just added to the original platform...
