OMGTIBE (Oh My God There Is Blood Everywhere)

PLEASE NOTE: This game is in a very early stage of developement. It is playable, but doesn't have that many features yet. Furthermore this game is not supposed to be the next Left4Dead. It's just a little game that I develope in my free time for my own amusement. Criticism and suggestions are appreciated, but please don't write hateful and unconstructive comments.

It's simple: Zombies are trying to conquer your house and you have to protect it - with your life and a machine gun. The Zombies will spawn faster the more of them you kill. You also gain walls by killing zombies. They are placeable and can protect you and your house. But be careful! You can't delete them after you placed them and you can't run or shoot through them.
