This is a fantastic game. Very few, nonintrusive ads, a whole lotta puzzles, cool designs... The controls are about as smooth as they get for a game like this, and some of the restrictions on how you can move things offer a more interesting challenge. The game itself runs very well, even on my older phone. Great for killing time or challenging spatial skills.

Very good concept with fun-to-solve puzzles, but the execution is a little flawed. The control interface works in theory but is definitely fiddly enough to make the move requirements for the stars feel cheap; Even if you know exactly how the puzzle works and how to solve it efficiently, it's another thing entirely to input that solution without misclicks, accidental movements, or cases of having to move a piece you've already removed *again* because you didn't move it far enough away from the puzzle for it to register as completely separated. IMO this concept really doesn't need the star-earning system anyway- Just mark off the puzzle if the player has solved it, and add an extra little icon if they manage to solve it in the minimum number of moves. The game is way shorter than I expected as well- the four packs (of maybe a dozen puzzles each) took me about a combined hour and a half to finish.
