Hi,
Fun game! I couldn't get the web version to work, but the download one did, albeit the screen was off to the top left for some reason. I really like the art style, especially the spaceman! It would be good to add a health bar to the zombies once they get hit the first time maybe to know that you're damaging them. Good controls as well, Great job!
If you get a chance to leave any feedback on my game too that would be much appreciated!
Cheers
