Fun, but caution advised
PROS:
Good story
Lots to do
Enjoyable puzzles, a bit above par
Good length
CONS:
In some scenes, if you don't get everything you need out right away, you can't get back in... and the game dead-ends without the needed item. For example, in the scene atop the train in the beginning, when going through the purse, be sure to take the batteries first, then the pill packet; otherwise, the wallet won't move over enough to allow you to take the batteries. Likewise, in the train station, be sure to find all three mural tiles or you can't progress in the next scene; be very thorough in each of the scenes just after you enter the station.
No map, but the hint button works well enough to lead you on where you need to go.
BOTTOM LINE: I really enjoyed this one, as I do most Alawar games.
