I actually beat the game... you just need to jump on top of the red boxes to be able to jump to the next platform :/ All of the levels are definitely possible.
I haven't doen the whole tutorial yet but I noticed that you told us to type "Background" but you typed "Backgrund"... sooooo that just confused me a little.
This was a very good tutorial... one thing though. If you could find a way to be able to highlight the code, so that people could just copy it it would be helpful. Unless you want them to have experience typing it on there own (Was that what you were doing?)
