Nice game, btw heres my susggestions
You know for some weird reason this game feels too unbalanced, and depend on if you were aimming for, very unrealistic. Most of the zombie games I have played have a sense of realisim, this one did not. Think Dear Rising, mall equals huge amounts of weapons, and stuff. Resident Evil equals limited weapon count, and certin number of items. If you would even suggest this realisim idea heres what I have. More floors in the cottage, zombies would not drop weapons, and health depending on what kind of zombie they are, Fire man= Fire Axe, Cop= Random weapon or bullets, Hospital staff zombie=Health though this one should be less likly to happen ;). And to balance everything out lets say the cottage would have First aid kits in some room to heal yourslef, and weapons or bullets deposits in it, seeing as how this person would have obviously prepared. As for the unbalance the room was made for zombie breakins, small, and obsticles everywhere, it would also be awesome if you could barricade the house doors with this stuff, and the doors should act as a early warning system instead of being WIDE OPEN!. Plus the game should tell you if a wave of zombies are coming i.e "You here foot steps, and the groans of the undead aproaching!", also why can't the charecter run! You should explain this or allow the player to run. Thats all I have hope that was helpful.
