It is a plants vs. zombies spin-off. An interesting idea that you can move your defenses after placing them, I still did not figure out if I like it. It enables me to have a set of strong defenders and just move them wherever the zombies come most.
Can not say that I particularly loved this game, why not buy the classic plants vs. zombies?
Anyways, issues/bugs I had:
1) Music continued playing once I clicked the main menu button of my phone. The screen went to my desktop but music continued. Check whether music always stop in your onPause.
2) Once I lost a level, the "play again" button does not always work. I pressed it several times before being taken to the menu.
3) I placed two hens one after the other, and there is something wrong with the graphics. The egg from the first hen appeared to fly UNDER the second hen. Sometimes it seemed that it flew above the hen body but under the hen's head.
4) I did not play until the higher levels, but do you have enemies that are not simply stronger zombies? I mean digging, flying, invisible, lane passing, whatever?
