Why not speed things up a little? more resources, more movement speed a little, for both player and zombies, to make it more of a fast-paced action game!
Days seem long, a way to check what time it is could help! As well as a couple of hours zombie-free, to invest in RPG aspects, while the rest of the time, fight like crazy!
Also, please insert a feature to inform the player of whats happening, like a log message that stays some seconds, such as "You have obtained scrap metal x1".
If the resource thingies could throw up recipes with a low chance, could help guessing the combinations, i guess
and cmon, let us see the pistol working
Good job man, the game was not perfect yet, not 100% playable yet, but i simply loved the way you finish well the features that are already there!
Everything that was there, seemed to work nice, which really made it taste better
I will have the pleasure to play your game through when there are more things, for now i will just experiment here and there because it gets boring without the action
