Get's boring and repetitive. It is on exactly the same format as so many games in the play Store... And as you get further into the game it keeps feeding you impossible to beat scenarios so that you run out of lives at which point they offer you the option to buy more. It doesn't really get harder, they just make it impossible to win more frequently, not unlike the arcade claw machines that only allow you to hold on to the prize after a preset number of tries and the number of tries increase.
