I wasn't sure if this game would hold my attention long but I was pleasantly surprised. The first few levels are pretty easy, but once you hit level 4 or 5 things become a lot more challenging. It is addictive, especially when you are only one second away from clearing the level. They offer in app purchases that allow you to skip a level, but if you're a true gamer, you won't bite. You'll want to do it the old fashioned way...through perseverance.
