They could have ended the game faster
When Alan comes back; The kids know at that point what the game does. So does Alan and Sarah....They should have just speed played the game.....Basically, whoever's turn it was, roll the dice, read the message, wait 5 seconds. LET THE NEXT PERSON ROLL. No where in the movie or rules does it explain you HAVE to overcome whatever happens....So let say Monkeys or Poison vines come out...Ok after you read the message, pick up the game, and run a good half a mile away from where you are, let the next person roll fast, Read, wait 5 seconds, run again, just keep rolling the dice for the player as fast as possible (NO CHEATING), and just keep moving. game could of been over in 45 minutes.
It showed this during the quick sand scene where Judy quickly rolled the dice.
