You know what's more fun than staircases? Monsters.
For the time being (and maybe even forever) I'm going to put aside multi-storey construction and focus on something a little more meat and potatoes. We're going to add Townseed's first monster next, as well as your survivor's first weapon. That's probably going to be a crappy constructable training dummy and a wooden club, but after THAT we're going to add the Bride of War.
Still working it out but I wanted you guys to know what I'm focusing on!
