Paranormal Investigators is Lock, Clock, and Peril's second game, and they definitely leveled up their set-building ability since Undercover Agent. The set was mildly ominous/creepy, but IMHO never got anywhere near scary (e.g. Halloween haunted houses can easily be worse) -- despite the theme, it's family friendly.
There's a variety of interesting interactions - nothing we haven't seen before, but well executed. Puzzles were reasonable. Another solid room, and I think a step up from their first.
Tanya was one of the most welcoming and friendly owners I've had the pleasure of talking to. She showed a lot of interest in what we thought of her games, and if we had any feedback - good signs that she cares about the player's experience. She and her husband clearly care not just about making great games, but building up the local escape room community.
Particularly interesting or different
No
4 was fine, though we breezed through it, so 2-3 might be better.
Physically active
Not at all
It's easy to find but a little hard to navigate to - you'll have to make a U-turn in front of an Air Force base, and then the turnoff can pass by quickly if you're not on the lookout.
