Nice job
I actually like this tutorial. I found it mainly useful for the function calls and implementation of how you did things since I know some programming. Maybe you could create separate scenes/frames for the in depth information instead of having to zoom in on it. Oh and from looking at the code you wrote for link's movement, he's supposed to be able to transition from one side of the screen to the other. But it only works walking off the stage from the left and up. He actually just stopped for the other two directions. Of course I didn't read the in depth information about it so I might have overlooked something you stated.
Overall a 5/5 for presenting useful information in a neat package.
