It was an addition that we made in response to some who were concerned about the validity of the contest. We added it as a way to let teams know that we aren’t going to do anything shady once they submit their games. If you are concerned about being disqualified for not submitting a Twitter post, don’t worry. 😀 We will be sending out an email this week to everyone who has registered - feel free to respond to that email and we would be happy to discuss an alternate means of submission.
Using Twitter was also just a way of having you guys get your work out there, and it makes it easier for us to help promote your projects with you. But totally understand where you’re coming from and we’re happy to work with you!
