Yeah it's probably not written anywhere for the game jam, however a README and License is a standard requirement for something that is open source (industry standard rather than "hackathon" or "game jam" requirement). I do need to honour those people that submitted on time and in full - hopefully it's all useful suggestions and feedback for the next jam. Nice work on adding in the license file now.
Seems like you had a lot of fun in this jam and kudos on trying out new tools and technologies. Hope you found it a useful experience. Good luck for the final announcements soon.
