The game is fairly good and has a nice concept, but needs more variations of attacks, buildings and ability to customise base a little more.
The animations for the attacks are all the same and when survivors attack another direction the animation is just mirrored. For example, Rick has one hand depending which way he is facing his missing hand changes.
The free coin system doesn't load at all when you try to watch an ad or find an offer.
The buildings change appearance ever so slightly every 3 levels or so meaning for a casual player it can take a couple weeks to see anything looking different.
Overall the game is fairly good, but some parts have been a bit lazy in creation and some aspects do not work at all.
