I liked some of the environment art and the models, though I was really confused as to what I was supposed to be doing or where I was supposed to be going until I explored enough to reach the end. The map is huge, but most of it is empty. The movement speed is too fast and the jumping is too high for the zombies to be an actual threat, and I could just casually walk away from them. There was also no feedback when shooting zombies until they suddenly died, so it was hard to tell whether I was hitting them. There also seemed to be a bug with the music and it just kept getting louder and louder until I had to mute the game. The UI on the left was also too small to see.
