On the one hand, I like the theme of the game but on the other hand, I'm not too crazy about the pay to play mentality. 5 tries is not enough and unlike Zombi Tsunami which allows limitless play, I find my playing this game less and less. In addition, it takes far too long to get past difficult levels and rewards are minimal. What used to be fun and engaging is now boring and redundant. Chances are that I will uninstall for something far more engaging and interesting.
