Yea I think that’s good advice for playing games or just working in teams in general. I used to do puzzle hunts, which if anyone doesn’t know, are kinda sorta similar to escape rooms and scavenger hunts (they’re very fun and I could talk about them at length and think video game puzzles could stand to steal from them). Anyway, the big rule we established early on is that everyone needs to think out loud. It’s not uncommon for someone in the group to say the dumbest thing you’ve ever heard in your entire life but have that be the thing that causes someone else in the group to find the solution
