Awesome! I just downloaded and have noticed that it's a bit tricky to place tiles on my iPhone 5 (though by level three I started getting the hang of it, and it's not actually hard, just a few mis-placements)—lots of little touches that really seal this game as great, the first I noticed was that you could switch two tiles place by dropping one on the other. The first 10 levels or so do a great job of ramping you into more difficult puzzles.
