GhostNet is a discontinued online multiplayer mod for Celeste. It was a buggy mess that somehow lived on for two years, and now has been replaced with CelesteNet.
This website lets you restart the GhostNet server a few more times until it'll be shut down forever.
Thanks, y'all, for sticking around for the last two years. Let's see what'll come next!
Please switch to CelesteNet immediately.
