I believe there is a fault in the counter. I have read the game and finish without killing any zombie. but it still state you kill one
another question would be if you call 911 not your wife and finished a day earlier, can you still finished the game?
also is there a possibility to bypass the page "your ear will ring for days"?
Many thanks to the complexity of the game. i finish it a year ago and still looking again, there are a lot of options.
