I really enjoyed what I played of the first game; this one has the added feature of enabling piece rotation on 1 or 2 pieces in every group if the player chooses to.
This important feature might get you out of trouble, to some extent, as it gives you more choices in which direction to place a piece. I haven't figured out if the provided pieces are of higher difficulty to compensate. There is a progression in odd pieces as you play higher levels.
As with the previous game, great graphics, relaxing music, and challenging gameplay.
