I really like the concept of this game, having to balance your attention between the 2 different aspects of the game was a good design choice. My only relevant criticism is that its pretty tough. Have you considered having a screen after losing that shows the questions that were asked and the players responses? It could add a bit of humor to the game for the players to know how poorly they were at conversing. It would also make it easier to progress in the game, as players would get familiar with the questions/answers faster.
