Hey there, person playing this right now.
I'm gonna save you some time.
The way to silence the town crier is kinda BS, and doesn't have anything to do with the time planning thing, so I don't feel bad about putting this here.
You literally hit the in-game mute button.
It's kinda clever, but I wish there was some kind of hint put in that it wasn't necessarily an in-universe solution.
Other than that though, this is an incredible game, and I'm glad to have been able to play it!
