I played this game for two reason: 1) It was given for free by PSN as a consequence of buying PS4 and 2) it is short enough to give a try a game I haven't heard about.
It gives me a good impression, It is game with a story behind that is beating by solving puzzle over and over again. Most of the puzzles are extremely easy , some makes you thing and a few are difficult enough.
I am very glad of having played this game to give a rest of too much shooters game.
The only cons were:
1) It doesn´t look to give take any advantage of PS4 potential (not even PS3). It seems a HD PS2 game.
2) Some bugs like Frame rate drops and freezing sometime.
If you had this game for free I recommend to give it a try.
Thanks for reading.
