This is a quite short game which does not take much time. The story is okay, there are some puzzles and an ending, and a solution to prevent getting stuck.
The story presents the player being stuck in a subway section, unable to escape from that place. The player has to deal with various items. The puzzles appeared a bit arbitrary to me -- I sometimes failed to see the causality of them -- I solved one puzzle and then something happened, and I did not necessarily find it related to my previous actions. So it was not always easy to find out what to do next, and I had to consult the walkthrough sometimes to find sense in what was going on. The aim is a bit unusual, one would expect that the player is supposed to escape from the tube station, and in the end he might succeed, but it is not explicitly made the purpose of the game. A player will maybe find the actual aim a bit unspectacular to feel motivated.
I can recommend this game anyway, it is surely a nice diversion, as long as you don't expect a masterpiece.
