Anything with zombies is a total win in my book.
I love the art style and the theme of being a survivor defending your house. The gameplay balance felt a bit off to me, though. It reminded me of an old Flash game I used to play called The Last Stand, which has a similar concept.
Anyway, I ended up cheesing the game by turning on the radio, picking off the first zombie, and then turning the radio off again. This let me slowly build up my in-game economy.
Well done on the game!
