This is a great game if you want to waste an hour or so clicking panels. I've probably spent more time playing this game than any other on my phone. I don't even have a problem with the ads, even though they may be slightly frequent. Buuuuut... The difficulty curve begins to flatten at the higher levels. I might be around level 230-ish, and it's starting to get a bit repetitive. Maybe some new concepts, And, on that note, on some of the levels it starts giving you limits on how many times you can move pieces, which puts an element of strategy into the game. Don't get me wrong, I'm sure many people would enjoy it. But I came to the game to click tiles and let my mind relax, not calculate the next move for ten minutes. And the new update didn't add anything but cosmetics, and the game looked fine beforehand. Overall, Good game, bad few updates.
