Can we get a host to clarify? I'm starting to get confused about where the line between just standard C# compiler stuff, which we of course aren't expected to implement ourselves, and premade libraries, which is cheating, is. I mean, unless SimpleJSON or any other JSON parser is in the Package Manager or built-into the Unity Engine or C# standard libary, then surely it breaks the following rule
*Everything* has to be made during the jam. This means you *can't reuse any code* or assets you made before the jam or *from other sources*.
There's nothing in the rules that says external code is ok as long as it's open source. That has nothing to do with it.
My only thought is: is SimpleJSON is a "generator"? In this case, it would be allowed because of rule 6: "Generators are allowed, as long as you have some control over the output."
