Understood. I do have some feedback for the event organizers.
The reason I did not provide a game design document is that doing so would publicly expose my email address. The entry form keeps email addresses secret, which I appreciate. But the decision to require game design documents publicly in the form of a Google Doc negates that, as Google Docs are documented as exposing the author's email address.
I understand that Google Docs were chosen for the judges' own security, but there should be some other solution that does not involve compromising my own privacy.
