Fun little time waster, worth the price, hard puzzles, overall a pretty good puzzle game worth its money, although the replay value is terrible, once you're done it gets boring, heck the same style puzzling gets pretty boring half way through the game. Another downside to this game is the AI, be prepared to swear, smash your keyboard and facepalm multiple times, basically the AI is extremely poor, they take the worst paths and you have no way to tell them to go another way, it brought me to bad frustration. So if you have a bad temper/ low intellegence, this isn't the game for you.
