I had a really fun time playing that one! It was actually kind of like my entry too, we both had a zombie thing. My favorite part though, was the soundtrack. That is my favorite type of music and to have it be played during those giant ambushes was really fun. I also liked the teammates the player has. It was fun to have allies.
But here are some things that I found in the game, Lag... There was so much lag. I thought it was client side at first but I saw some other comments and saw it wasn't. Also, during the barn part, there were a bit too many zombies for me. The shear amount of zombies with the lag made it almost impossible there.
with all of that aside, I would like to wish you luck with getting this a full steam release! Also, please check out my game too if you have time!
