Deserves negative stars

This game has glitches out for the fifth time today and of those five times were my nightmare mode and you only get 5 a day...The map doesnt function right and the server connection is terrible I will frequently be forced to continue alone because of "Connection error"Which isnt me because my wifi bars on the screen are full green.Your lucky you got a 1 star from me.
