Every complaint I've seen about this room is valid. It is absolutely a 90+ minute room to do in 60 minutes and out of all of 13th Gate's rooms, this is the only one we felt less thrilled and more anxious/exhausted by the end of it despite finishing with 5 seconds remaining. There's a few easy things they could do to fix the trouble points and considering it's been years since its release and they keep getting the same feedback, I'm assuming they're not looking to change things. The iPad was useless, the flashlights we got didn't always work, I don't love working almost entirely through journals, and I'm really glad our GM (River) contributed as much positivity to our room as she did.
That said... The set - DAMN. The puzzles - DAMN. The wow factors - DAMN.
