Shoot da Zoombies!
Excellent game! Graphics were high res considering the close to 3D point of view. Every weapon was useful (except for the shield and the two guns, both placed on the key 1).
Here is a hint for some of you who can't beat the game: If there is no enemy on the screen, which means that you are looking away (use left or right) they can shoot as much as they want and you won't get hit. Use this to beat the game without the help of Jewski.
Come to think of it, the cheats are a nice gimmick but nothing special.
Anyway, if you're going to release a sequel, please involve a level in a big skyscraper at night (that means you have to make levels either completely in day- or moonlight) also with Zombies that are a bit more intelligent that the ones I saw in this game. The regular ones can be taken out easily with the Sniper, but I love sniping so I don't care too much about the headshot thing, which still makes sense at any rate.
Keep em coming, you've already been favorited.
