I hate doing this, this will be the first time I rating anything under 5 stars. However I feel that was the enough effort you should be able to beat these games without spending money on Boost or whatever else, unless you really suck at the game. I have beaten all levels without spending money. Then came level 162 I've played at least 50 lives and 1 and a half hours of free lives and can't get past it which has been one of the most frustrating things I've ever played. Ĺĺ3uxadhhqjaxx
