Great to play it once in a while, but it can hook you.
The thing is that this game seems not to have a way to beating it, I could be wrong but It just doesn't feel it has an end or goal in sight, which is a little turn off for me but also takes some load off you back since this game get's challenging as time goes like any other puzzle game.
At the end this game is very well put together, and today for a few dollars you can purchase this and have a unique experience. If you have any attraction to puzzle games, this title will most likely keep you on your toes.
