I wasn’t in class the day that we played Keep Talking and Nobody Explodes but I have over 15 hours on it from the past few years playing it with my friends at school.
I really like the idea of the game being 2-players but not within the actual game. Having 2 specific roles, one of the defuser, and one as the instructor adds a fun dynamic and not knowing what the other person is seeing makes things really exciting.
I find myself always wanting to be the defuser for the earlier rounds because it’s easier, and then switching to the instructor because when it comes to the memory puzzles, I do a very poor job.
