Too much drinking?

I noticed that in the most recent segment, the three made a LOT of mistakes, largely because the puzzles required reading and paying close attention, which they refused to do. I think this was in part due to the large number of times they drank for the drinking game (Doctor). I would recommend making sure to add personal limits to the drinking game, because intoxication and trying to solve difficult puzzles is frustrating for everyone.

I think something similar happened in the final part of King's Quest VI iirc.
