Great Idea. A nice new take on an old concept
The design on the top screen, music and second colour of the honeycombs are configurable and playing through the modes opens more options up. This is a nice touch and some of the designs are pretty cool.
In a nut shell this is a must have for fans of puzzle games and equally a good starting point for people new to the genre, since the first few puzzles are pretty simple and encourage you to keep going.
With it's $20 price tag it's certainly worth every penny.
