This game seems pretty good! One issue I ran into was the loading system. It's really awesome that we are given a chance to reload quicker if we are fast on the 'r' key, however to do so we would basically have to let go of one of the two controls. If that were fixed, I would score this game 4 1/2 or perhaps even 5.
Other than that, great great game! Loved how you could aim for different parts, and the zombies would change how they moved based on that
