Yes Pigs vs Wolves may be cheaper but it is way far from plants vs zombies. Controls suck too much. You tap on a square but the unit appears on the squre beside it. At first I was thinking I was the one making mistakes but after placing units again and again on cells i dont intend to put them even when I touch the screen carefully I gave up on the game. I think that is why they have the eraser in the controls since you will need it. Sadly it does not reimburse coins and you end up dying due to the mistake.

Placing units are also slow. Ive tapped the screen several times before it responds. Overall I think the development is more designed to favor the Wolves. This game is way far from plants vs Zombies. As they say you get what you pay for. This game is a real sucker.
