Reminds me of Colin Baker's Doctor and Mel aboard the spaceship and their adventure with the Vervoids (sp?) - it has that same claustrophobic feel. Here, instead of lying about their motives outright, the participants have the luxury of using 'The Murder Game' as a cover for their true actions. The only thing missing is Polly forcing carrot juice on Troughton's Doctor! Unlike others who have voiced trouble in visualizing the Second Doctor in character, I actually could hear his Troughton-esque ramblings and rumblings. I also enjoyed Ben's uneasiness of character in playing dress-up, and Polly's enjoyment of same. Overall, an appealing adventure!
