Where is the voice setting located in the game?
The voice setting can be found in the side menu under 'How to play', at the bottom of the page in the Voices section. There are three options: let them speak by themselves, only when you ask, or no voices at all. This setting is saved between playthroughs.
Why can't I access the Dead Ford quest?
The quest to step towards the centre of the ruins at Dead Ford is currently blocked due to a bug. The internal flag required for this quest does not get switched on in normal gameplay, causing you to see 'There's nothing here'. This issue has been fixed for the next version and can be temporarily resolved by opening the browser console (F12), pasting the following code, and hitting enter: SugarCube.State.variables.personajes.voz.eventos.presentada = 1. After doing this, walk somewhere else and return to Dead Ford where you should see 'Step towards the centre' and continue with the story.
