I was wondering if I could make my game open source before or after submitting.
The submissions are expected to be open source, so I'd say definitely :P
Awesome, thank you!
The submission requirements say it needs to be submitted as source, but there's no guidance as to licensing. If I didn't want to licence the code for others do use would I need to?
Sorry I missed this comment somehow. License the code how you desire, as long as we can build it ourselves for purposes of evaluating the submission.
