Sloppy..
First of all, zooming in doesn't zoom in, I don't like that. Uploading a beta of a flash game is kind of... stupid. Upload it when it's done, if you have a beta, get your friends to test it or something. Survival would be better if the zombies came towards you, and you actually zoomed in. I can't really give advice on how to make it better, because there isn't much to judge. The tutorials alright I guess, but there's not much to the game, add special ammo or something. During the loading screens, the pictures are kind of hard to read because of low resolution. For a loading screen, what would work well is just a solid background, and on the loading/tip bars, there should be another, solid colour behind the text. Makes it look nicer. The controls are kind of annoying, I have to put my left hand in an awkward position to play. The controls would be better if it was something like: R to reload, W to zoom in, S to zoom out, or something along those lines. Good try, though. Work on it, it'll probably be great when it's done :D.
