Just because sometimes some things aren’t as clear as you thought they’d be.
Q: I’m just one person, I can’t test a multiplayer game! When I try to play myself, it says “name already in use”.
A: Go to server.txt and edit your name. Each time you click host or connect it reads data from this file. So you just have to change it by alt+tabbing to it.
(Will make edits if more crazies pop up!)
