It is a fine game. It is basic as an auto runner is. The catch is that you have an army of dumb zombies. When I mean dumb I mean that they fall mid jump. That is a challenge and not a bug (if it is, don't fix it devs). This would be a good game but I can't stick with the game. For one, the missions range from easy so luck based. The daily challenges are not enough to keep me interested and the gimmic is not (yet) fun. I grew tired of this and jumped to Jetpack Joyride because that is better.
