"Why do people post about multiplayer every day? The dev has said he doesn't plan on adding it. If you want it there is already a mod being made for it because the game does already have mod support. The multiplayer mod was working with the one of the last versions i believe but it was buggy."
-A reply to the literal previous feedback post that was also about multiplayer.
TL;DR: dev doesn't plan on official multiplayer, but there is a mod for it in the works
