Game was kind of fun. Esp soon as I learned I could use one bullet to take out a whole row of zombies. Trying to get in place to catch the bullet added a nice mechanic to it. My only feedback would be some type of animation or visual to know I was getting attacked. I was too focused on the middle of the screen to notice my health bar going down. And since the bar outline is black on black it's hard to tell how full it is at a glance.
