I've been having a lot of trouble interacting with the game.  While using the smoke box; the logs, food items, and smoke/stop buttons don't always work.  I have found that holding left mouse works more often than just clicking, but still not 100% of the time.  I have managed to clear all the smoke clouds, but I'm unsure how to progress.  I suspect that each person wants a specific combination of wood and food smoked by them, but haven't found the way forward yet.
