I've owned this game for nearly 10 years now and only just now gotten round to playing it.
It's a wonderful brain teaser that has a comfortable difficulty and is just as punishing as it should be in its puzzle resets.
Absolutely wonderful time and it didn't make me frustrated at all which i think is a testament to how relaxing and reasonable they all are.
Such a wonderful game that is great to relax with a simple puzzle game session.
i beat it in one sitting but i would wholeheartedly say its worth the price.
