To the OP: if you feel that this knowledge imparted in the context of a 72-hour hackathon is of any importance, I have to question your overall context. A hackathon is a social event with some potential learning involved. Any decent product and/or idea is going to have to survive beyond a 72-hour window. Your contributions during this timeframe, compared to the overall success/failure of a product, are meaningless. Not trying to bash here, just recommend you don't overthink it. Go the hackathon, be a cheerleader and have a good time. And take the opportunity to sell all their mobile games as a challenge to yourself, much like a salesman's interview: sell me this pen!
