Not being able to move away when attacked by zombies has been the cause of many deaths, but it makes sense, I mean I imagine that the zombies grab hold or something while they attack. Also gives a god reason to not let the zombies reach the character.
Can't tell how much points I get, because it seems that much of the screen is taken up by the chat window, and I don't know how to make it go away. Still... it's a good game.
