I think the old game was so trivially easy to win as the Gatekeeper if you actually wanted to win, that I don't know that any additional rules are needed. It really only makes it harder for terrible Gatekeepers that aren't playing to win anyway.

Edit: I assume the downvotes are from people who disagree with my claims on gatekeepers. If you do disagree I would like to hear why. Keep in mind I am talking about this as a game.
