Your first? Looks like a promisingly good start.
First things first.
CHAINSAWS ARE OVERRATED! (they'd get stuck in the zombies)
The limited ammo on some of the guns meant I only used them for one level to see how they worked.
Shotgun almost got me killed (so both were only used for one level each)
Uzi was the best weapon in my opinion (50 shots compared to some of the 30 shotters)
And the rifle's single shot (while powerful) makes it a terrible weapon against a horde of zombies at close range, with runners.
Now with those out of the way.
Excellent game.
The fact you had multiple styles of zombies was a plus.
The fact you had multiple styles of survivers was a plus.
Losing survivors while searching was annoying, but at least it means your group is taking a risk when leaving the barricade.
I usually hate the fact that the smaller guns are useless in these zombie games due to the fact people have the zombies die from damage, not a shot to the brain. Noticed that your zomibes dies faster from being hit in the head (like a good zombie should).
I didn't play with the sound on, so giving a 5 to give points.
Overall. Good luck with a sequal, and no matter how long people beg/bug/threaten you to release another game (sequal or not), take your time. As we've seen with this. You did take your time, and it was time well spent.
Good luck, and hope to see more from you.
I'll shut up now.
