Platform tutorial V.1.3 This is bad...real bad...
Many tutorials these days seem to do the same thing, show you some big piece of code and tell you to paste it and everything will work. Well, you could have at least explained the code and told us why you HAVE to press down to "land". I don't think you really understood that code and just found it on some website...
You also could of made if easier to view the code....like opening it in a new window perhaps? Also, the code you are using is very amuteur for collisions and won't work well with objects that aren't rectangles. An explanation of the code(which was lacking in quality), decent graphics, and decent collision detection could of made this much better.
