Once all things in game are unlocked it can take up to ten minutes to clear out ones to-do list in the game, which is too long of a time to spend just to get started on other things in a mobile game. Mobile games are best in small pieces of time, but once the player has to spend too much time on tedious tasks just to accomplish anything else in the game it is just too much time to spend at that point and looses its appeal.
The design of the controls for the game are implemented quite well where using any of the menus or planting on ones farm is intuitive in function. It is pretty obvious that care was taken to make sure the game operates the best it can on a touch device.
Being a casual game a descriptive tutorial is necessary so that anyone who picks up the game can understand the mechanics fully. Farmville 2 does a really good job at this with the first hour of the game basically being a full on tutorial that explains all of the basics in an informative manner.
OS notifications, in game notifications, constant asking to send messages to ones Facebook friends, basically a barrage of nagging in order to propel the game into everyone's life.
Much of the game is centered around interaction with other Facebook users, so those that are already ingrained in Facebook's system will have no trouble getting help in the game trading goods or just teaming up to add neighbors.
In a game where precise controls are key when planting crops or plowing specific areas of fields it is a bit disheartening to see the controls of Green Farm being imprecise, which makes for a frustrating experience when one has limited resources that take a long time to earn be wasted on imprecise actions that result in accidental placement of things.
The games is constantly tasking the player with new things to do, which can keep the game fresh as there is not only something new coming up but it is something that requires different gameplay elements such as creating mutant zombies out of ones normal zombies or planting all kinds of different crops. Then there is the fact that one can fight with their zombies, which adds a new element over traditional framing sims.
Like most free to play games Zombie Farm 2 is addictingly fun at first for a couple of hours, but then a wall is reached and most actions become extremely difficult to perform without spending real world money on items to help the play bring the difficulty back down to a playable level.
