This is a great game and a great way to kill some time and relax. 2 stars given as the owners have ruined the game by placing adds right in the middle of levels. You're in the middle of playing a level and you're forced to watch an add. You lose your focus and the game isn't so enjoyable anymore. I realise owners have to make their money through advertising but you don't have to show adds in the middle of the game. Be fair. Not sure I'll keep playing for this reason only.
