this took a while to get to the real core of the mystery, I think it was around ep7 when suddenly it picked up and from that point I couldn't miss a single moment that I binged this in 2 days

since the mystery revolved around one big plot as apposed to both The Great Escape and Busted, they had too much empty time where they sat around and talked again and again about their clues and I think that was boring. they did 1 puzzle then talked about it for half an hour
but after the murder happened more and more tension and excitement happened

though to be honest, I'm way better than them xD kim ssam was obviously evil while poor dokgo ssam seemed nice (and totally forgotten! did he die?), and they took too much with some of the clues, like the sleeping gas thing, as soon as I saw the bottles even before knowing the ending I wanted to say "take that with you!", there was a scene like that in TGE and they actually planned ahead, but since most of these ladies never experimented "escape room" variety show (beside Park Ji Yoon, I've missed Crime Scene TT_TT)
and the whole flip switch as well, they just needed to tell jae jae the 8 sets and the 3 outside could've dealt with it by crossing out the ones that didn't match, visuals are easier than listening

they also need to separate them more often, there seemed to be obvious power struggle, bibi and yena felt left out (either the others wouldn't let them or they'd think they're not good enough), but both did pretty well on their own
Park Ji Yoon had more experiment so she tried to go the comedic side more, Jang Do Yeon as well is full on easy going she was ok with being smart or not

though I do wish they'd not use such hightones just to sound younger, we all know they're not teens and that's the funny part, they strained their vocals too much

otherwise Jung Jong Yeon never disappoints and it's always nice to see female centered plots
