Awesome game
You did a great job on this. You have even done better than some experts that have been making games and movies on NG for a long time, also considering this is your first submission. Everything I liked but there could be some more additions like:
Selectable days or pre-selected days: Like if you select longer time periods there is a greater space in happenings or more happeneings.
More happenings (example [these are meant to be the guy talking into a recording device]):
I have fought off the first wave of zombies. I have to search the town for something better to defend myself with. I have to leave my friends in the safety of the barracade while I search the town with my only defence being a (selected weapon). Since this is the first night I should expect plenty of survivors to be about. It seems quiet......DAMN IT I SA......(in this time I think the character should engage in a hand to hand fight against a zombie)
On my search I heard gunfire, I ran toward the scene to discover another group of people in a losing struggle against the zombies. Should I help them? (you decide whether to help them and gain allies or to run back to the safety of your home)
There are too many zombies here......he must be close.......I have not told my friends of my discovery but they will eventually find out. We are piling into the truck......................The truck is on the move...............(there is a cutscene from the back of the truck of what appears to be vampires running after the truck) Open fire!!!! (a battle of you and your allies against the closing horde)
Cheats should also be put in I say. Like to get all weapons.
More abilities like dual wielding.
Enemies with guns.
More allies to help you with any amount: like you could give them jobs. Like military soldiers would be best suited for defence. You could have people repair the barricade or provide medical assistance or build cover.
Possibly a romance between the main character an a survivor.
Choosing a character.
You made a great game for NG and I'm really surprised (I am hoping to be able to make games and movies too but I am still trying to find out how).
Good luck in any future productions.
