Finished it on day 84. Never found a portal though, will play again

 

Cured zombiism on day 90, got everything by day 128.

 

This game is seriously fucking awesome; it's almost impossible in Nightmare, barely accomplishable on Harder.

Does anyone know if there's a sequel or a remake out there of this game? Flash game artists tend to do that quite a bit, apparently.

 

There is now.

Playing through, but there doesn't seem to be too much different... just a little snazzier. A couple of new endings.

 

I got excited because I thought there was a zombie game I haven't played before, but was disappointed this one is very good though, I spent a few days during classes slugging through it on all difficulties. I don't think I've played the second one yet though, I'll have to check it out.
