Roadmap
This roadmap is to give a general idea of where I'm trying to take Sandbox Zombies next.
That's all I want to share for now. I have a long, long list of other features and improvements I would love to see in the game, but just the items above amount to a great deal of work already. I might sneak some other things in here and there, but this roadmap will be my main focus for now.

If there's anything you'd like to see in the game, shoot me an email at feedback@sandboxzombies.com to let me know.
