This feature was back-burnered because we didn’t want to release it until we had something that worked for text-answers too - as that’s more “pure” version of Family Feud. Where players actually have to think of the answer and type it in, versus having a multiple-choice set of answers (which would make Family Feud way easier).
We never completed the work on the text-answer support for this as we moved on to more pressing issues.
We’ll probably focus on getting a full Family Feud style feature out in June or July, after our April and May update.
