After round about 200 Levels the nice little game, which is perfect for a short and comfortable coffee break, vanishes and turns into an simple and annoying pay to win game. Of course playing is free, but without using tons of boosters you can forget about playing through a few levels in some minutes. You'll need a lot of tries to manage only one "easy" level only to get to the next really hard one. Dear Users, spend your time with nice things but not with this "game"!
