I don't really think this fits the theme very well, but it's a cool idea and well-executed nonetheless. The art and sound are both really well done, and I was having fun with it for a bit. My only gripe is that the controls aren't super great. Having to press instead of being able to hold is a little tedious. Also the length that the shotgun sits away from you makes it a little difficult to shoot things at time.
Overall, it's a neat little game.
