It says "Since BLitzMax uses a garbage collection system ... don't rely on a *CONSTRUCTOR* beging called at any specific time." This should be DESTRUCTOR :-)
Oops, sorry about that. It's fixed now. :)
Update: Now static methods (a Function within a Type) and static fields (a Global within a Type) are included in the tutorial.
I think it's mostly complete now. Let me know if you find any errors, or think of something important I missed.
