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
if it's not working, i'm probably editing it :P I've been trying to make a perfect one for ages-this isn't strictly perfect, but it's good enough :) it now can detect the angle of a slope- it gets the angle of the legs according to the slope- it will for more animations soon-once I've made it work :P if anyone wants to remix it, no need to ask. There is one thing you need to know though: instead of using the 'switch to costume' block, you should just change the variable 'costume' to the name of the costume that you want to use.
