Very fun, very challenging. It's everything I hoped! Flawless design and seamless game play (minus the ads of course?)

I really like it this game because it challenges me to think outside the box.

Sweet! The only nits are that the levels between devices don't sync (although the game is Game Center-connected), the advance-to-next-level button is often obscured by the puzzle, the animation for switching to next level is frustratingly-slow, and ute preference is reset every time you restart the game Otherwise I'd give it 4 stars.

I really like the game and the fact that it teaches me. I really love that DURING Challenge Mode there are skip-free ads! During the ads the timer still runs, and I just started playing Challenge Mode!
