This one has you going from subway stop to subway stop solving escape room-esque type puzzles, each station also represents a significant moment-in-time of a young girl, Laura's life -- infancy, childhood, school, love, loss, etc.. I believe her mother dies tragically and she goes a bit crazy for it, but I might be reading into things somewhat.
The game does a great job in not being overly obtuse with the clues, but I did find myself on occasion trying the old "try every object on every thing" tactic to get past a few things that didn't quite make sense.
A good two hours spent.
