This is an amazingly designed game that was built to last for sure. The design in this game is incredible. Each level brings its own little surprise with it. There are a ton of levels that will last you a decent amount of time.A cool part about the game is the fact that it is challenging on half of the levels, but then the other half of them are nice and easy. This is great because after you finish a really tough level, or if you are still in one, it is nice to do an easy one to cool your mind for a little bit. In the car, this is a great game to play because it does not require Wifi, and it takes your mind off of the fact that you are in the car for another 2 hours:). The little things in it count too, like the incredibly soothing music and sounds made in the game. When I first installed the game, I was a little scratchy by the fact that it was said to be really challenging, until I realized that the challenge is what makes the game fun! I would definitely install this game if I were you!
