Great game but some advice for changes

I dont get crashes here which is great. I would like an option to increase the inventory spaces so you can bring more weapons which would be helpful. Also I feel like some zombies just randomly spawn behind me when they were not there a second ago so whats with that? Also I was not able to play any multiplayer games because it couldnt find anyone so Im stuck on single player. Overall great fun game!
