Just played your game, I love the art style, the zombies are beautifully designed and I love the mechanic of having to wait until the gun was lined up before shooting. It taking place on the ship was a fun choice. For criticism, I'd say that I'd love to see a tutorial of sorts before playing, as I was confused. Also there was no wall collision, both myself and the zombies could float and attack wherever. Overall, I still love this idea of having to escape a ship of zombies, maybe adding a timer so that you gotta leave before you sink would add to it. Overall great job! keep it up!
