There's a line in rules which says:
"Your game must have a Linux build".
And I've got question: Can I build game to Java Bytecode, which will run under JVM on Linux? Is it allowed?
Of course it's splitting hairs. Python can (and probably should) be compiled into a native binary, however. That's why I brought the basic/dosbox example up, which describes the essential problem here better. Another issue could be anything web-based.
"Native" is also a generally problematic as a term, especially on the Unixes.
I don't think technicalities like that will disqualify anyone.
