Excellent Work
Day 211 - Win by Cure
9/10 5/5
I noticed a slightly annoying glitch during the announcement of Horde Attacks. It didn't slide over to the location, but rather jumped, and made it very difficult if not impossible to locate your fort again. Possible fix would be an arrow or marker pointing at your fort, a jump to fort option, or having it slide over to the horde attack marker, rather than just jump the screen.
Aside from that, you lose just a bit on the art for the zombies during attacks, but otherwise a solid game. The only other issue I saw was that the survival and +Defense researches didn't seem to do much for me, though it may have been based on how far in I was.
Now, if you'll excuse me, there's a queue of Zed lining up in the shooting range... Keep up the good work.
