maybe add an AFK warning, if you don't move for too long or you just hold S or Down Key it brings you to a menu after like 5 minutes or even 1 minute.
That would work, but we'll end up adding a whole AFK checking system just for an accessory.
Serenitrove is meant to be a chill experience, and I know some players (me included) like to go AFK sometimes just to let the Gramophone play in the background. An AFK prompt might end up feeling kind of out of place for that.
