great looking game.
But the game play isn't hard, its unfair.
you cant have zombies that take so many bullets with limited ammo.
also the melee attack is almost completely useless as the zombies don't stumble back enough for it to be safe. the katana has too much wind up time, making it more useless than the bat. The flamethrower's hitbox is too far out in front of the stream to make it worth using. I can go on for ever.
you should have beta tested this.
