I used to play the game on Facebook using my desktop. But that game doesn't work anymore. I spent a ton of money playing it on FB and was eagerly looking forward to chapter three which never came. I am now replaying chapters 1 and 2 on PC using the Big Fish version which is greatly modified from the original and does not include the newly released survival mode. I cannot play the game on phone or tablet - it's too small and I can't use my fingers and hands like that. I must play on PC. When will survival mode be available for PC?
