what you need to do for 1-3 is kill an animal before you grab the key. then when you do grab the key, land on the body. after that, move onto the left of the dead body and it moves to the right. its slow, but this gets you it with one death.
haha. i got blinded, then lit on fire, then just as i got done being blind, another one hit me, so i was blind again and i somehow ran into a stickie and saved myself. Awesome luck there.
The guide does work. When it says infect a few countries, I infected 8-10 and that worked for me. For some people, it's not working and I hope that helps.
